VMBGP4 Momentary with delayed on


How can I simulate a momentary action with a delayed on?

I want my heater to come up when I’m sure my valves are open. I now use a pump delay with a momentary action on the pump output for the heater contact.

Normally, I’d just use the Micro-Switch within the values to close the circuit to the heater / boiler, with maybe a relay contact in line with them to isolate the boiler.

This way, you can trigger the values during the summer to stop them from seizing, without switching the boiler on.

Otherwise, I’d cascade the relay actions, rather than look at adding a “delay on” to the glass panel.

You might need to use a virtual relay half way in the solution to make use of the momentary function.
