My Zeroth unit is not reaching the target heating/cooling temperature, why is this?

Heating or Cooling Not Reaching Temperature

If your Zeroth unit is not reaching the target heating or cooling temperature, here are a few simple checks you can carry out before seeking further assistance:

1. Check the wall thermostat
   • Ensure the wall thermostat to set to the desired room temperature and time setting. If the timer does not allow sufficient time for the heat pump to run, the room may not reach the desired temperature.
   • Adjust if required.

2. Look for warning messages
   • If the “System Fault Contact Support” message appears, further guidance can be found here: Zeroth Fault Message Article

3. If still unresolved
   • Contact the building management service that looks after your heating system.
