Heating + electrical heating

Use case

Your customer has a combined heating system with 7 zones. Five zones are equipped with a zone valve controlled by a thermostat. Two zones are equipped with electrical heating controlled by a thermostat. A circuit pump is optional.

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 THT7).

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

  3. Create a heating system (H/C1).

  4. Create the electrical heatings (HEAT1 and HEAT2)

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

    • Select the heating system (H/C1).

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

    • Define the heating zones. Combine the correct thermostat with the corresponding zone valve (THT1 and VALVE1, THT2 and VALVE2, ..., THT5 and VALVE5).

    • (optional) Create notifications.

  2. Create a routine Electrical heating (ROUT2). Use the following behaviour, select the electrical heating and corresponding thermostat per zone (HEAT1 and THT6, HEAT2 and THT7).

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 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 (*).

a heating or cooling module 4U (MOD2)

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

  • the heating system H/C1 (contact 5 of the module) (**) (***).

a heating or cooling module 4U (MOD3)

  • the zone valve VALVE5.

  • the electrical heatings (HEAT1 and HEAT2).

(*) 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.

(***) The contact closes when one of the thermostats demands heating.
