Abstract: An electrical control system for an absorption heat pump capable of conditioning a space by cooling or heating including:(a) a unit activation component 64a having an on and off position responsive to temperature in the space to be conditioned;(b) a mode selection switch 64e having a heating mode position and a cooling mode position;(c) safety switches 64c for sensing hazardous operating conditions;(d) a timer device 60 which is activated by the unit activation component 64a and the safety switches 64c and which, after a predetermined period of activation, turns an output 64 to an on position;(e) a first control circuit 68 for operating the outside fan 15a when the unit activation component 64a is in the on position;(f) a second control circuit 69 for operating the solution pump 30 when the timer output 64 is in the on position;(g) a third control circuit 70 for operating the second or chilled coolant pump 12p when the timer output 64 is in the on position;(h) a fourth control circuit 71 and 71' for moving a
