Environ Installation
Your thermostat is a precise instrument; please handle it
with care.
Turn off electricity to the HVAC system before installing or
servicing the thermostat or any part of the system. Power
can be disconnected at the circuit breaker or at the HVAC
system.
Do not turn electricity back on until work is completed.
Do not short (jumper) across electric terminals at the
control on the furnace or air conditioner to test the
system. This may damage the thermostat.
All wiring must conform to local codes and ordinances.
This thermostat is designed for use with 24VAC and millivolt systems with a
separate 24VAC power adapter.
The thermostat relay load should be limited to 1.0 amp.
Higher amperage may cause damage to the thermostat.
You will need a small Phillips screwdriver and a drill with
3/16-in. (4.8mm) bit for wall mounts.
Location
Replacement installations: mount the
Environ in place of the thermostat. You
must have a C wire or other 24VAC
power available at the Environ location. A
new location will require moving your
wiring.
For new installations and for re-locating
the Environ, follow these guidelines:
x
Locate the thermostat on an inside
wall, about 5 ft. (1.5m) above the
floor, and in a room that is frequently used.
x
Do not install it where there are unusual heating conditions, such as:
in direct sunlight; near a lamp, radio, television, radiator register,
fireplace; near hot water pipes in a wall; or near a stove on the other
side of a wall.
