Eliwell IDPlus 974
Refrigeration controller for compressor, defrost and evaporator fans with three probes and HACCP alarms.
The Eliwell IDPlus 974 is a refrigeration controller that switches the compressor, defrost and evaporator fans of cold rooms and display cabinets. This Modbus RTU template reads the probe temperatures, alarms and relay status and lets you start a defrost, switch to economy or standby and change setpoints from ModbusCloud.

If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show the cabinet and evaporator temperature of every cold room on one ModbusCloud dashboard.
- Get an email alert when the cabinet temperature rises above a set limit or the alarm word is not 0.
- Keep a temperature history per cold room to show the food safety inspector.
- Start a manual defrost from ModbusCloud when an evaporator ices up.
- Raise or lower the setpoint of a display cabinet remotely when the product range changes.
Installation
Connect the 5-pin TTL port of the controller to an Eliwell TTL to RS485 adapter and wire its A and B to the ModbusCloud Gateway, with termination at the bus end.
On the controller set PtS to d (Modbus), and set FAA and dEA so FAA x 16 + dEA gives a unique address of 1 or higher.
Leave parity at none and stop bits at 1, or match them in ModbusCloud; power cycle after changing the parity.
In ModbusCloud, add a Modbus RTU device at 9600 baud with that address and import this template.
Check that Probe 1 Temperature matches the value on the controller display.
Things to watch for
The controller does not answer. What should I check?
Check that PtS is set to d (Modbus) and not t (Televis), that the address FAA x 16 + dEA is not 0, and that baud rate, parity and stop bits match. Swap A and B on the adapter if needed and add termination at the end of a long bus.
Why do I get errors when reading many parameters at once?
The controller answers short messages only and reads parameters one register at a time. Poll only the parameters you need and keep the poll interval relaxed; the probe and status values are the ones to read often.
Why does writing a command have no effect?
Commands such as defrost, economy, AUX and standby are accepted only while a short timer runs. Write a number of seconds to Command Window Timer first, then write the command value within that time. Parameter writes change the cooling at once, so check the value before you write.
Why does the status word show a large number?
Status and alarm values are packed as bits in one word. The register comment says which bit means what, such as bit 3 of the compressor word for compressor on.
Can I connect several controllers to one bus?
Yes. Give each controller its own adapter on the RS485 bus and a unique address through FAA and dEA, then add each one in ModbusCloud as a separate device with this template.
