4. Installation
4.1 Location
The 202 is designed for installation in climate controlled living spaces.
Place the unit in a central location with good circulation.
For proper temperature sensing, avoid exposing the 202 to heat radiated from
lamps, sun light, fireplaces or any other radiant heat source.
Avoid locations close to windows, behind doors or alcoves with poor air
circulation, adjoining outside walls, or doors that lead to the outside.
Select a location that prevents the 202 from being directly exposed to air
currents from supply registers or ceiling fans.
Mount the Control on a section of interior wall that does not contain hot or
cold water pipes or duct work.

4.2 Mounting / Installation
Follow these steps to mount the 202 Control to the wall. 1. Turn OFF all power
to heating and cooling equipment. 2. If an existing thermostat is being
replaced:
a. Record color and terminal marking of each wire.
b. Disconnect the wires from the existing thermostat being careful not to
allow them to fall back into the wall.
c. Remove the existing thermostat from the wall.
3. Pull the thermostat body off the thermostat base. Forcing or prying on the
thermostat will cause damage to the unit.
4. Move base over hole in wall and mark mounting hole locations on wall using
base as template. (See Fig. 1)
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 to wall. Leveling is for appearance only and will not
affect thermostat operation.
6. Connect wires to terminal block on base using appropriate wiring diagram.
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.
8. Two “AA” alkaline batteries are included in the thermostat at the factory
with a battery tag to prevent power drainage
9. Remove the battery tag to engage the batteries
4.3 Battery Location
FIGURE 2.
IMPORTANT:
·
Leveling Thermostat
Leveling is for appearance only and
·
will not affect thermostat operation.
· 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.
Do not exceed the specification ratings.
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
Battery Location
Premium AA alkaline batteries are required when C-wire is not available. When
C-wire is available, the batteries provide a back-up source of power (this
will maintain the clock in the event of a power outage).
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 between Y 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 ” ” is displayed the batteries should be replaced
before leaving.

in proper position to engage safety interlock or door switch
4.) Tighten Connections
Verify thermostat and system wires are securely attached. Diagnostic: Set
System Switch to Heat and raise the setpoint above room temperature. Within
five minutes the thermostat should make a soft click sound and “Heat On”
should appear on display. This sound indicates the thermostat is operating
properly. If the thermostat does not click, try the reset operation listed
below. If the thermostat does not click after being reset, contact your
heating and cooling service person or place of purchase for a replacement. If
the thermostat clicks, contact the furnace manufacturer or a service person to
verify the heating system is operating correctly.
1.) System Switch not set to Cool 2.) Loose connection to thermostat or system 3.) Cooling System requires service or thermostat requires replacement
Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. Same procedures as diagnostic for “No Heat” condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling if the compressor lock-out option is selected in the installer menu. (see INSTALLER MENU, item 50)
Possible short in wiring, thermostat, heat, Check each wire connection to verify they are not shorted or touching other wires. Try resetting
cool or fan system
the thermostat. If the condition persists contact your HVAC service person.

Display can be adjusted +/-5°. See User Menu item 04
Digital thermostats provide precise control and cycle faster than older
mechanical models. The system turns on and off more frequently but runs for a
shorter time. If you would like to increase cycle time, choose SLO for slow
cycle in the Installer menu. (Reference menu items 30 & 35) If an acceptable
cycle rate is not achieved, contact your HVAC service person. 1.) See
corrective action for “No Heat”
2.) See corrective action for “No Cool”
3.) Replace thermostat
4.) Make sure keypad lockout is not turned on (denoted by icon)
