Controllers and methods for controlling operation of a climate control appliance for heating and/or cooling a space are provided. One example controller includes a memory for storing at least one temperature offset and a processor coupled to the memory. The processor is configured to receive the reduced operation request from at least one of a utility provider and a user of the controller, to receive a sensed temperature from at least one sensor disposed within the space, and to determine an artificial temperature based on the sensed temperature and the at least one temperature offset associated with the reduced operation request. The processor is configured to, in response to the reduced operation request, operate the climate control appliance based on a comparison of the set-point temperature and artificial temperature during a reduced operation interval, to thereby reduce operation of the climate control appliance in response to the reduced operation request.
