Need advice- wiring room thermostat for use with tube heater

[nibbles]

Hi all, my first post on here (though have dipped in and out for a couple of years for advice), so be gentle with me!

I'm a fairly competent DIYer having undertaken a good few major projects in my life, including a kitchen extension a few years back from rewiring to plumbing and everything in between (before the reg's became so strict and complex ).

Anyhow, I'm looking to wire up a 120w Redring Suntube heater via a Sunvic TLX9201 room thermostat to provide controlled frost protection/background heating for the dry side of our aviary.

As I say, I understand the basics of electrics - but every time I look at the three wires of the tube heater and supply then at the four terminals in the thermo' - my mind just goes blank!!! I seem to have forgotten more than I ever knew.

Any help would be much appreciated

Oh, the terminals in the thermo' are marked as:

1 common
2 satisfied
3 demand
4 connect to neutral

Supply wires:
Live - terminal 1
Neutral - terminal 4

Heater wires:
Live - terminal 3
Neutral - terminal 4

Terminal 2 is not used.

The two Earth wires connect together in a separate connector block.

Supply to 1 & 4, load to 3 & 4.

Don't forget to sleeve & join the earths.

Where are you taking the power from?







EDIT - too slow....

Thanks to you both, my cockatiels will are very grateful that they won't perish on those cold winter nights!

Now you've explained it, it makes perfect sense.

The supply is via an IP55 socket provided by a sparky who knew what he was doing so is fused and via an RCB etc

Cheers again guys
