Your thermostat is a precise instrument.
Please handle it with care.
Turn off electricity to the appliance before installing or
servicing thermostat or any part of the system. Do not
turn electricity back on until work is completed.
Do not short (jumper) across electric terminals at
control on furnace or air conditioner to test the system.
This will damage the thermostat and void your warranty.
All wiring must conform to local codes and ordinances.
This thermostat is designed for use with 24 volt AC and
millivolt systems. The thermostat should be limited to a
maximum of 1.0 amps; higher amperage may cause
damage to the thermostat.
On replacement installations, mount the new thermostat in place of the
old one if possible.
On new Installations, follow the guidelines listed below.
Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the
floor, and in a room that is used often.
Do not install it where there are unusual heating conditions, such as: in
direct sunlight; near a lamp, radio, television, radiator register, or
fireplace; near hot water pipes in a wall; near a stove on the other side
of a wall.
Do not locate in unusual cooling conditions, such as: on a wall separating
an unheated room; or in a draft from a stairwell, door, or window.
Do not locate in a damp area. This can lead to corrosion that will shorten
thermostat life.
Do not locate where air circulation is poor, such as: in a corner or an
alcove; or behind an open door.
Do not install the unit until all construction work and painting has been
completed.
This thermostat does not require leveling.
