Switch off a pump - how to delay

Beitrag von blueznl » 14.12.2014, 16:43

I'm fooling aroudn a bit with my Homematic setup, before actually installing it all. I'm missing some valves, so I have to wait anyway...

I have the following setup:

- wall thermostat HM-TC0IT-WM-W-EU
- TX Radiator (channel 2) has a direct connection to a Radiator Valve HM-CC-RT-DN
- TX Actor (channel 7) has a direct connection to a Power Switch HM-ES-PMSw1-Pl (channel 1)
- the power switch is switching a pump on and off

This is what I want to accomplish:

1. Valve opens when warmth is required - works
2. Pump starts when warmth is required - works
3. Pump stops when warmth is no longer required - works
4. Pump keeps running for a few minutes before switching off - doesn't work

I was expecting an option when setting up a direct connection between Thermostat and Radiator Valve and an actor such as the Power Switch where I would be able to set up a 'switch off' delay. Is this possible?

Is there a way around, for example using a program in the CCU2?

(Feel free to reply in German or Dutch, can't write it but I can read it.)
