The thermostat housing feels
hot to the touch
When working at full capacity, the thermostat
housing may reach a temperature of approx. 45°C
to 50°C (113°F to 122°F). This is normal and does
not affect the operation of the thermostat.
The thermostat is rated to operate safely at these
temperatures; ensure that the thermostat is not near
heat sensitive or flammable materials such as exposed
wood or wallpaper.
The heating system is constantly
running
Make sure the temperature is not set too high.
The heating system seems to cycle
too often
Make sure the selected cycle matches the heating
system (see pages 7 and 8 for details).
