5. Move base out of the way. Drill mounting holes. If you are
using existing mounting holes pull thermostat wire bundle
through the hole in the thermostat base. Mount sub-base

7. Push excess wire into wall and plug hole with a fire resistant
material (such as fiberglass insulation) to prevent drafts
from affecting thermostat operation.

Leveling Thermostat
Leveling is for appearance only and
will not affect thermostat operation.
All wiring must conform to local
and national electrical codes
and ordinances.
•
This control is a precision
instrument, and should be
handled carefully. Rough
handling or distorting
components could cause the
control to malfunction
Gas/Electric Switch
If the system is a heat pump or electric
furnace, the GAS/ELEC Switch must be
set to Electric. If your system is a gas or oil
furnace, the switch must be set to Gas.
RC/RH Jumper Wire
This thermostat electrically
connects the RC and RH
terminals so a jumper
wire is not required. If the
application provides a
separate wire for RC and
RH, clip the RC/RH jumper.
This will isolate both

terminals so they can be
independently used.
O/B Terminal Switch
The O/B switch on this thermostat is factory set to the O position. This will accommodate the majority of heat pump applications,
which require the changeover relay to be energized in Cool. If the heat pump being installed requires a B terminal, to energize the
changeover relay in Heat, the O/B switch must be moved to the B position. To enable single stage heat pump operation a jumper
must be field installed betweenY and W. The 202 does not support auxiliary heat.
4.4 Battery Replacement
To replace batteries, set system to OFF, remove thermostat from wall and install the batteries in the rear along the top of the thermostat
(see Figure 1). For best results, use a premium brand “AA” alkaline battery such as Duracell® or Energizer®. If the home is going to be
unoccupied for an extended period (over 3 months) and “
