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.
Procedure
Creating the controls and the devices
Create the thermostats (THT1 to THT7).
Create the zone valves (VALVE1 to VALVE5).
Create a heating system (H/C1).
Create the electrical heatings (HEAT1 and HEAT2)
(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
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.
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) |
|
a heating or cooling module 4U (MOD3) |
|
(*) 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.
