Detailed description

The MagIQtouch BMS Industrial Controller M1 acts as a bridge between a cooler and an external building management system. It accepts input signals for functions such as unit on and off, operating mode, manual drain, emergency auxiliary control, and set fan speed, then returns status information through outputs and LEDs.

The enclosure includes a DIN rail retainer on the back and can also be fixed to a wall using the supplied wall brackets, plugs, and screws. The controller provides terminals for communications, 24Vdc power, two 10V power-out points, emergency auxiliary wiring, digital inputs, analogue inputs, digital outputs, and analogue outputs.

Two 10Vdc output terminals can be used by the installer as a convenient power rail for switching or pull-up applications. The 0V return is internally linked to the power-out 0V terminal, which simplifies common signal wiring.

Safety

Installation and maintenance should only be carried out by trained and qualified personnel and must follow local and national wiring rules. The controller is for indoor use only, and the wiring between the controller and the building management system must maintain reinforced insulation from live parts.

The unit is a 24Vdc SELV device and must only be connected to other SELV circuits. Damaged cables should be replaced by the manufacturer, an authorized service agent, or another suitably qualified person. Children and people with reduced physical, sensory, or mental capability should not use the appliance unsupervised.

A risk assessment should be completed before work begins, especially when the installation involves working at height. The mounting location should provide safe access, proper clearances, and enough space for cables and terminals.

Setup and operation

Installation preparation

Before starting, isolate the cooler from its power source. Choose a mounting location with room for DIN rail or wall mounting, enough clearance for digital and analogue wiring, a dedicated 24Vdc power input, and a position within 100m of the cooler. Do not use power boards or double adaptors.

The controller can only operate one cooler. Systems with more than one cooler need a separate controller for each unit.

Communication cable

The supplied communication cable should not be modified. Approved cable lengths are available in different options, and the total run from cooler to controller must not exceed 100m. Using altered or non-approved cable can affect operation and may void warranty coverage related to cable changes.

Mounting

For DIN rail installation, hook the top catches onto the rail first, pivot the controller downward, then secure the lower catches until it clicks into place. For wall mounting, fit the two wall brackets to the enclosure, mark and drill the fixing points, insert the supplied wall plugs, and screw the controller to the wall.

Cooler connection

Connect the RJ 6-way communication cable from the cooler CPMD to the controller. Electrical installation must follow the applicable safety and wiring regulations for the cooler and the controller.

Power connection

The recommended power input is 24Vdc. The controller accepts a DC supply in the 12V to 30V range with current capability from 1.25A to 10A.

Emergency auxiliary

If the building management system requires emergency auxiliary control, wire the emergency input according to the diagram so that an isolation signal shuts down the cooler. If emergency auxiliary is not used, the required links must be installed so the cooler can operate normally.

Digital input signals

Digital inputs use 0 to 10Vdc signals. Low is defined as 0 to 2Vdc and high as 4 to 32Vdc. Recommended control voltage is 10Vdc. The unit accepts inputs for cooler on and off, operating mode, manual drain, supercool on supported Climate Wizard models, and emergency auxiliary enable or disable.

Unit on/off: controls cooler power state
Cool mode / fan-only mode: changes operating mode
DRAIN: requests manual drain or force drain
D1 function: indirect-only or indirect plus direct cooling on supported models
EMERG AUX: enables or disables operation

Analogue input signals

The set fan speed input uses a 0 to 10Vdc analogue signal. A potentiometer can be used to vary the input and set the target fan speed. The analogue input ground must be tied to the power-out 0V terminal.

Digital output signals

The controller provides relay-contact digital outputs for error status and drain status. These outputs are open or closed contacts rated at 24Vdc and 1A. Spare digital output channels are also present but are not used.

Analogue output signals

The actual fan speed output reports fan speed as a 0 to 10V analogue signal. A reading near 0V indicates the fan is off, while 10V indicates maximum fan speed. Spare analogue output channels are also included but are not used.

Diagnostic LEDs

The front panel includes error status and error code LEDs. When a fault is detected, the error status light turns on and the error code LED flashes in a pattern that identifies the problem. Error codes can be cleared with the reset button on the front of the controller.

Common error indications

1 flash: communication failure
2 flashes: failure to detect water at probes
4 flashes: failure to clear probes during drain
7 flashes: incorrect supply frequency

Troubleshooting

If the cooler does not respond, first confirm that the controller is powered correctly, the communication cable is properly installed, and the wiring matches the required signal types. Check that the emergency auxiliary input is not inadvertently disabling operation and confirm that any required links are fitted when emergency shutdown is not being used.

If an error LED is active, use the flash pattern to identify the fault area. Communication faults, water probe detection problems, drain-related failures, and supply frequency issues are the primary coded conditions described for this controller. If the issue continues after checking wiring and supply conditions, the cooler manual should also be reviewed because error behavior can vary by product.

Warranty

Warranty coverage is not stated as a time-based term in the available material. The documentation does note that product failure caused by modified supplied cables or non-approved cable use is not accepted under the manufacturer’s warranty.

Pros & Cons

Pros: Direct BMS integration for one cooler, clear LED diagnostics, flexible DIN rail or wall mounting, and useful digital and analogue signal handling.
Pros: Built-in 10V outputs make control wiring simpler for installers.
Cons: Limited to one cooler per controller, indoor use only, and requires careful compliance with SELV and wiring rules.
Cons: Communication cable length and cable type must be respected to avoid reliability and warranty issues.

Faqs

What should be checked before installing the MagIQtouch BMS Industrial Controller M1?

Before installation, confirm the controller will be used indoors only and that a suitable mounting position is available on a DIN rail or wall. Make sure there is enough clearance for the input and output wiring, the controller is within the allowed cable distance from the cooler, and a dedicated 24Vdc power supply is ready. The cooler must be disconnected from power before work begins, and installation should be done only by trained, qualified personnel following local wiring rules.

Can the MagIQtouch BMS Industrial Controller M1 control more than one cooler?

No. The MagIQtouch BMS Industrial Controller M1 is designed to operate one cooler only. If the system includes more than one cooler, each cooler needs its own compatible BMS controller. This is important for correct communication, proper signalling, and reliable operation. Trying to use one controller for multiple coolers can cause control faults or wiring issues, so the controller should be matched to a single cooler setup.

How is the MagIQtouch BMS Industrial Controller M1 mounted on a DIN rail or wall?

The controller can be mounted in two ways: on a DIN rail or directly to a wall. For DIN rail installation, hook the top catches onto the rail first, then pivot the unit down until the bottom catches click into place. For wall mounting, fit the supplied wall brackets into the enclosure base, mark the fixing points, drill the holes, install the wall plugs, and secure the unit with the provided screws.

What communication cable is required for the MagIQtouch BMS Industrial Controller M1?

The controller uses a 6-core flat communication cable from the cooler controller to the BMS unit. The manual warns not to alter supplied cables and notes that the maximum allowed communication cable length is 100 m. Using non-approved cable or modifying the supplied lead can affect performance and may void warranty coverage. For best results, keep the cable run within the specified limit and use the correct connector type.

How do you connect power to the MagIQtouch BMS Industrial Controller M1?

The controller is powered by a dedicated 24Vdc input, with an accepted voltage range of 12 to 30Vdc. The manual recommends using a proper 24Vdc supply and avoiding power boards or double adaptors. The power terminals include 24Vdc input and 0V connections, and the unit also provides 10Vdc outputs for signalling and control tasks. All wiring should be done carefully to comply with electrical safety requirements.

What are the 10Vdc output terminals used for on the BMS Industrial Controller M1?

The controller includes two 10Vdc power output terminals that installers can use as a small power rail for switching, pull-up voltage, or other control signals. The combined current capacity for both outputs is 500mA, so they should not be overloaded. The 0V terminal is internally linked to the output 0V reference. These outputs are useful for low-power signal circuits, but they are not meant for heavy loads.

How does the emergency auxiliary input work on the MagIQtouch BMS Industrial Controller M1?

If emergency auxiliary control is used, applying the isolation input will shut down power to the cooler. This lets the BMS stop the unit in an emergency or safety event. If emergency auxiliary is not required, the manual says the supplied links must be fitted so the cooler can operate normally. Leaving this input disconnected without the required links may prevent the cooler from running, so this connection must be set correctly during installation.

What do the diagnostic LEDs and error codes on the controller mean?

The controller has diagnostic LEDs that show error status and flash codes for faults. A steady error light indicates a problem, while the flash pattern identifies the type of fault. The manual lists examples such as communication failure, failure to detect water at probes, failure to clear probes during drain, and incorrect supply frequency. Errors can be cleared with the reset button, but recurring faults usually mean the wiring, probes, or cooler setup should be checked.
