Central Heating

[CarolLadd]

Hi,
I have an old Honeywell thermostat (30 yrs) and when I tried to replace it it blew a fuse, so I have put the old one back on but now the heating comes on in the day or night when the timer is switched off. The program timer is British Gas UP2. Can you help me please!!!!

You have jumbled up wires. Take cover off and take a picture then upload it.

Hi,
I have uploaded picture of thermostat as requested.
I also need to say I returned the new stat and I have put the old one back on.

A 6060B
Wiring should be common 1 satisfied 3 and 2 is a neutral.
You may have fused the contacts on the timer when you blew the fuse (you made a live to neutral short).
Get someone who knows what they are doing to help you.

Tamz did the 6360B take over the 6060B

1 live in
2 N not normally use only for accelerator resistor
3 on (NC)
4 off (NO)

The 6160b (the brown one) was in between Tony but the wiring has stayed the same numbers over the years. Always a good idea to use the neutral for the anticipator if there is provision for it. Makes the stat more responsive.
