Claim 0:
1. A controller configured to selectively set a reversible heat pump assembly in either a heating mode or in a cooling mode, the controller comprising a control circuit configured to:
for a time period, determine, using a demand determining function, a heating demand for heat to be delivered by the reversible heat pump assembly and a cooling demand for cold to be delivered by the reversible heat pump assembly;
identify, using an evaluation function, simultaneous heating and cooling demands, wherein the evaluation function is configured to use the heating demand and the cooling demand as input data;
generate, using a control function, a control signal indicative of whether the reversible heat pump assembly is to be set in either the heating mode or in the cooling mode, wherein the control function is configured to use the heating demand, the cooling demand and the identified simultaneous heating and cooling demands as input data, wherein the control signal is generated such that, in response to identified simultaneous heating and cooling demands, temporarily setting a heat pump of the reversible heat pump assembly to deliver heat at an output greater than an output indicated by the heating demand, thereby reducing a heating duty cycle and/or temporarily setting the heat pump to deliver cold at an output greater than an output indicated by the cooling demand, thereby reducing a cooling duty cycle; and
send, using a transmission function, the control signal to the heat pump of the reversible heat pump assembly.
