  2. Turn off the thermostat, all electronic devices and any electrical devices (e.g. heater) which will be connected before installation and maintenance.
  3. This product should be used in conjunction with a NTRL LISTED Class 2 power supply. Operation from other supplies may result in a potential fire risk.

Installation location
The thermostat should be mounted on an inner wall 1.Sm (-5 feet) above the floor in a position where it is readily affected by changes of the general room temperature with freely circulating air. Prevent direct exposure to sunlight. Do not place this thermostat at a location where air circulation is low, or where it is subject to frequent temperature changes (e.g. near a door). Do not place the thermostat near heat generating sources (e.g. radiators, hot air vents, TV or lights). Do not expose the thermostat to moisture. Do not expose the thermostat to dipping or splashing.

Opening
Pull out the battery drawer and then lightly press on the spot shown below in order to detach the front shell from the base.Robertshaw-
