A single thermostat can be used both to control heating and cooling.
- Setup separate temperature regulator (hysteresis or PID) for both heating mode and cooling mode
- If the required temperature (setpoint) differs a lot from the actual temperature, you may want to increase the speed of the fan. Equation smart rule does the job.
- Fan speed is only activated when also the respective valve has been opened by the temperature regulator (hysteresis or PID)
