Cooling
Use case
Your customer has a cooling system with 5 zones. Each zone is equipped with a zone valve 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 THT5).
Create the zone valves (VALVE1 to VALVE5).
Create a cooling system (H/C1).
(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 cooling system (H/C1).
(optional) Select the circuit pump (PUMP1).
Define the 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 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 (*). |
a heating or cooling module 4U (MOD2) |
|
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.
(***) The contact closes when one of the thermostats demands heating.
