Heating and cooling

Use case

Your customer has a heating and cooling system with 5 zones combined with a heat pump. Each zone is equipped with a zone valve controlled by a thermostat.

You can also use push buttons with LED(s) and comfort sensors instead of thermostats, or a combination of both.


Creating the controls and the devices
  1. Create the thermostats (THT1 to THT5).

  2. Create the zone valves (VALVE1 to VALVE5).

  3. Create a heating/cooling system (H/C1 and H/C2).

  4. (optional) Create a circuit pump (PUMP1).

When there is no circuit pump in the installation, there is no need to configure it in the software.

Creating the routine

Create a routine Heating/cooling per circuit (ROUT1). Use the following behaviour:

  • Select the heating/cooling system (H/C1 & H/C2).

  • (optional) Select the circuit pump (PUMP1).

  • Define the heating/cooling zones. Combine the correct thermostat with the corresponding zone valve (THT1 and VALVE1, THT2 and VALVE2, ...).

  • (optional) Create notifications.

Filling the cabinet and addressing the devices
  • You can only address four zone valves to a heating or cooling module 4U. Contact 5 of the module is an H/C-contact.

  • Always address the heating/cooling system to the first heating or cooling module in the cabinet (contact 5).

Fill the cabinet with ...

and address the following devices ...

a switching module (3x) 2U (MOD1)

  • the circuit pump PUMP1 (*).

  • the heating/cooling system H/C1&H/C2


a heating or cooling module 4U (MOD2)

  • the zone valves VALVE1 to VALVE4 (contact 1 to 4 of the module).

  • the heating/cooling system H/C1&H/C2 (contact 5 of the module)


a heating or cooling module 4U (MOD3)

the zone valve VALVE5.

(*) You can also address the circuit pump to the H/C contact of another heating or cooling module.

(**) This contact is not physically used in the installation. You can address this contact also to another heating or cooling module. This contact is used for switching the heat pump from cooling to heating.

(***) This contact is not physically used in the installation. The contact closes when one of the thermostats demands heating or cooling.
