:confused: I just replaced an older Honeywell T87F (round and non-programmable) thermostat with a NOMA Programmable 52-2558-8.

The Honeywell had the following wires (connections):
R
RH
G
Y
W

The NOMA has the following connections:
H2
H1
B
O
RC
RH
G
Y
W

There is a jumper for the RC and RH.
Is the Honeywell Red the same as the NOMA RC?

I've replaced two older thermostats with newer ones (Ritetemp brand) and I've always found the correct info in the instructions.

If the instructions are not in the NOMA literature then you best contact NOMA.

I wish you the best.
