Programmer or Timer Clock
If the heating system is not controlled by a mechanical
thermostat, but by a programmer instead, the HUB
Controller can replace the programmer or timer clock.
No Thermostat or Programmer
If there is neither a mechanical thermostat nor a
programmer or a timer clock controlling the heating
system, the HUB Controller may still be compatible.
