The TRM & CTR towel rails must not be switched on/off by an external timer or FSCC / FSCW towel rail controller. Whilst the towel rail can have an isolation switch, it is not designed to be switched on/off at the mains supply repeatedly every day. The TRM & CTR towel rails have integrated thermostatic and timer controls, so external switching is not required.
If the towel rail is switched off at the mains supply for more than three hours, the next time the towel rail is powered on, it will have lost any PIN code set and the current time (the memory is a backup capacitor). It will prompt you to enter the current time before it will then be able to operate.
