I’m trying to replace my current thermostat (Honeywell CT3611) for a ZTS-110 thermostat. I have a heat pump for cold and hot air and a furnace which should kick in as second stage heating. It’s supposed to heat alone when external temperature is -12 Celsius. I believe this is achieved on the furnace itself with a trigger from the electric meter outside (higher electricity rates apply when outside temperature is below -12).
I attached the picture of the current wire connections.
Here is what I tried on the ZTS-110 (in this setup, stage 1 doesn’t seem to heat and stage 2 only kicks the Heatpump in, not the furnace):
CT3611 - COLOR - USAGE - ZTS110
C - light blue - Common - C
R - Red - 24V - Rh/Rc
W2 - White - Aux Heat Relay (Furnace) - W2
E - Brown - Emergency - N/A (left it unplugged)
W1/Y - Yellow - Compressor(Y) and Stage 1 Heat Pump Relay(W1) - B/Y
O - Orange - Cooling Relay (Heat Pump) - O
G - Green - Fan Relay - G
JUMPERS : HPUMP and HE

Can someone tell me what I did wrong?
