central heating control

[wez1981]

Hi all,


Not sure if this should be in the electric section or the Central heating?


I have just finished the water side of a central ehating install, I am quite please I have tested up to 2 bar with the pump on and no leaks, so know I am thinking about the control side. I have a danfoss TP 9000 and am now a little confused as all of the circuit diagrams I can find have a change over valve, which I don’t need as my water heating is still electric. Presumably I can just connect pin 4 (heating on) to the swithched live on my boiler???



TP9000 Timer


L –Live in FROM 3A Fused spur

N-Neutral in

1-DHW OFF (not planning to use)

2-HTG OFF

3-DHW ON (not planning to use)

4-HTG ON

5-REMOTE SENSOR

6-REMOTE SENSOR


Many thanks for your help

In a word - yes.

However, depending on your wiring situation,

you can either connect a room thermostat to the 'remote sensor' terminals, or -

pin 4 to thermostat and then to boiler (I would assume you then need a link between remote sensor terminals. I cannot look up the instructions on the device I am using at the moment).

thanks for the conformation the Timer came with a temp sensor and you can set room temp on the timer, which I quite like the idea of, hotter in the morning or evening for example.
