observed.

Temperature Limiting Pins
Temperature Limiting Option is for applications where the temperature
setting of the control is to be set and "protected" from unauthorized
adjustment. To limit the temperature range, follow the directions below:
1. Remove cover from thermostat.
2. On inside of cover, firmly press small tapered end of a pin into the
approximate maximum and minimum temperature positions.
3. After pressing pins into place on inside of cover, rotate temperature
knob to be sure the knob is between the pins.
4. Replace cover on thermostat. Check that knob rotation is limited in
travel as set by the pins. If rotation of knob is outside of limits, check
that the pins are installed properly.
5. Install supplied screws at top and bottom of thermostat to secure
cover.
Pins are shown installed at
60 and 65˚. The temperature
setting range is limited
between these two
temperatures.

What is the dead zone of a thermostat? Verified

Many modern thermostats have a dead zone. If the temperature deviates less than 4°C from the set temperature, the system will not heat or cool. This so called dead zone of the thermostat prevents the system from turning on and off too often, saving energy.

What is the best place to mount a thermostat? Verified

The best place for a thermostat is approximately 1,5 meter above the ground. Never place the thermostat nead a radiator or other heat emitting equipment or in direct sunlight. Choose a room that is used often. In most cases this is the living room.
