Salus rt310 and R478 Thermo-electric actuator
- Thread starter ijusufi
- Start date
The Salus has voltage free contacts NO and COM. meaning that they can be used to switch different voltages. At the moment it already has something connected to these terminals, will those wires be removed and the new actuator replace them instead? If they are not being removed, we would need to know what the wires that are in NO and COM are connected to at the other end. Also, what voltage is the new actuator.
And the wires in NO and COM are they staying, and if so what is on the other end of them?
Why do you have a brown Live wire in a Neutral terminal?

OK, so if you are only wiring the actuator to the bare Salus and not connecting anything else.
yes but you have a brown wire in the N terminal
I asked about that already 
but I think you may have missed my edit.
but I think you may have missed my edit.with this connection the salus functions in the opposite. For example, if the temperature in the room is 22 °, if I set the temperature to 25, the water will stop circulating, then if I turn it to 20, then the water will start circulating ... please can you help me
This model of Salus will only provide a live on the NO (normally open) when heating is required. If it's operating in reverse, then you will need to either:
1. Change the type of electric actuator / valve for one that works in reverse of the one you have now. I assume the one you have now closes the valve when the thermostat turns 'on', if so you require one that opens the valve when the thermostat turns 'on'.
2. Change the thermostat to one that also has an NC (normally closed) or 'Heating off' connection that becomes live when the heating isn't required, as per the example below, and connect the actuator live wire to NC instead of NO
