Wireless Electrical Relay

[Neil O'Connor]

Anyone ever hear of a wireless electrical relay?

I am upgrading my heating controls to have 3 zones.
2 Rad zones and 1 HW zone. As this is an upgrade i am going wireless to avoid running cables. I already had a 220v supply in the hot press and was able to use wireless programmable thermostats to control the motorised valves.

My problem is in order to do the job right i need to have the motorised valves sending a signal to the boiler to bring it in when ever they are open.
There is no hope to run a cable to the boiler so what i want is some sort of wireless relay.

i.e. when the N/O volt free contacts in the valve are closed the relay transmitter picks this up sends a signal to a receiver relay (at the boiler) which closes it's volt free contacts (engaging the boiler).

Anyone ever hear of such a thing?
Seems simple enough (similar technology in fact to the wireless thermostats).
Cant seem to find anything on-line though.

You could try the radio controlled relay here (on page 2 for the relay)
Cannot vouch for them but am currently trying to persuade a customer to have them.
Electric centre do them as well, but they are much more expensive.

More information here but they are more expensive than scldirect

Is the new valve in close proximity to the existing valves & wiring centre???

You may not need a new cable to you boiler if you can get at the connection of the existing valves....
