My house trailer has only electric heat. I have added the "A" coil and heatpump. I have replacaed the two wire thermostate cable with a five wire cable. One goes from the thermostate to the furnace the other goes from furnace to the outside unit.
I'm using the two heaters as the aux heat.
I have a Honeywell Cronotherm III thermostate.
I have added two relays for each of the heating elements.
I am using the origonal relay (sequencer) for the fan.

I need to know how to wire the thermostate to both units.
For example does W on the thermostate go to the W in the furnace and outside unit as well.

Or just tell me how to wire the unit

Can you furnish the wiring diagram for the thermostat?

The thermostat is a programmable unit Cronotherm III
These are the terminals R; C; O; B; G; W2; W1; Y1; L

The furnace has no identification since I have rewired the controls, but I assume the fan will be "G" and each of the heating elementgs "W1 and W2" respectively

The outside unit had the following terminals and I will give the place they go to on the control circuit board

Y ----- T1 and Y
O----- O
W2 --- W2
R --- R
E --- goes through some adjustment device that has these markings 20; 40; 45 and back to R

I hope this helps and thanks for the answer
