Heatpump Optimiser X not calling for heat unless setpoint is set high
I have a heatpump optimiser x and two tado x temperature sensors, one upstairs and one downstairs. These are setup in rooms as required and are able to change the temperature setpoint on the heatpump optimiser. The issue I have is that the heatpump optimiser does not turn on the heating unless I set the setpoint high, >25deg C. For instance the downstairs temperature sensor is currently set to 20deg c and the measured temperature is 15deg c but the heating is off. Any ideas?
Many thanks.
