wiring my new thermostat

stranger12

Hi all,

I am trying to change my honeywell analog thermostat with a wireless thermostat .

My current thermostat is
http://www.honeywelluk.com/products/Temperature-Controls/Temperature-OnOff-Control/T6360-Room-Thermostat/

my new thermostat is salus rt500rf
http://www.salus-tech.com/products/thermostat/rf-thermostat/_c1_34_wireless-programmable-room-thermostat-868mhz/

blow is the diagram of my old (current thermostat )


1 or brown is live as tested with my multimeter

2 and 3 are both neutral and can't work out the difference between them . when I put the multi meter probe on 2 the voltage is higher than it is with 3 . on three it is around 200 and on 2 around 230.

From the diagram , I think the coil symbol and the rectangle symbol between 2 and 3 means resistor , right ?

The new thermostat has a relay and then the wireless thermostat
now the relay , I have Live , Neutral, Normally open and Com(Linked live feed) connection ports.
The picture from the manual is below.



Now I connected the live to live on the new relay and pin 2 from the old thermostat to neutral and left 3 out . The relay came on but was not sending any signal to the boiler.

I swapped 2 with 3 so this time I have 1 (live ) and 3 neutral connected with 2 left alone . The boiler came on permanently and the thermostat was ignored.

what do I need to do ?

Many thanks

Get someone in that knows what there doing or you’ll likely just blow the thermostat if you haven’t already ?:rotfl:

Match the new thermostat receiver unit to the wiring diagram of the boiler, don't try to reverse engineer the old thermostat

if you disconnect the wires from the stat (with power off) and put in connector blocks you will find which are which

prob find a 3 core and earth so red=live blue=neutral yellow=switch

i would say u need to put live to 2 and link 2-3 with a link wire (any off cut) put neutral to N and switch to 1
