I changed thermostat in summer time. It is heating pump in condominium - Whalen VI-A-401-BO
From WHalen mercury thermostat (with red,yellow,blue and green wires connected to respective terminals R,Y,B,G).
To Honeywell RTH2300. AC was working fine in summer. Heating does not work.
Could you suggest wiring, please.
