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.
Wiring
There are 4 wiring terminals at the back of the thermostat which are labeled as “Y”, “G”, “R” and “O/B W”. The recommended wire range is (AWG) 14-22. Do not use metal conduits or cables provided with a metal sheath.
