Replacing Honeywell stat T6160B with Sunvic TLX 7501

[aolcot]

Hello,
I intend to replace a very old and battered looking honeywell stat with a more modern digital version.
Unfortunately i cannot find any wiring diagrams for the old honeywell stat so before i start, i just wanted to hear from experts out there on this forum who would be willing to share some of their advice and knowledge.
The current stat (Honeywell) has this configuration:
Pin 1) - Red Wire
Pin 2) - Blue Wire
Pin 3) - Yellow Wire

The new stat (Sunvic) has this required configuration:
Pin 1) Off
Pin 2) On
Pin 3) Common

So my problem is that i can't fully match the existing coloured wires to the new stat pin confirguration without the honeywell wiring config. So can anyone point me to an online resource that has such information on the old honeywell model or can someone simply map the three colours (based on the old model configuration as, before i get shot down in flames, i am aware that colours on their own mean nothing).

Many thanks in advance.

There may be a drawing inside the honeywell cover.

thanks for the suggestion, but there is no diagram on the old unit unlike the new stat.

londonboy:
thanks for prompt reply. I'll isolate the blue off and wire up tomorrow. Thanks your help.

Let us know how you get on.

Honeywell say for your old stat
1 common
2 neutral
3 demand

So connect as londonboy says.

your new stat is battery operated and switches across your Red and Yellow wires, the blue neutral is not required.

so New stat

Red to common
yellow to on
Blue Neutral safely sealed off

'londonboy': I think you've stated those terminals about face - as the O/P has also done:-

The red (line) to the Honeywell 'stat on 'common' should go to the new 'stat terminal marked 'C'.

The yellow on the old 'stat terminal '3' should go to the new 'stat terminal '2' ('ON').

The blue core on terminal '2' of the Honeywell 'stat should be insulated and tucked away safely, as it isn't required on the Sunvic 'stat.

Terminal 3 ('Off') on the Sunvic, isn't normally used on standard systems.
