I am installing a programmable Noma 52-2570-6 thermostat (upgrading from a previous FHP Manufacturing Thermostat that wasn't to our liking.
When taking the old thermostat off,
G -green
O - orange
Y with jumper to W - yellow
C- black
R - red
My new thermostat requires:
RC
RH
G
Y
W
Can anyone help me? This thermostat is hooked to Earth Energy furance unit in an apartment complex with a ground water source heating and cooling system
THANKS! Jim
