POWER FAILURE
7,Whenever the main power is interrupted or fails, the battery power retains and current
time. This thermostat has permanent memory, although you will have to reset your clock
when there are power outages.
POWER SUPPLY
8,The thermostat shall be powered by 24 VAC and with batteries as backup.
BATTERY WARNING
9,Fresh alkaline batteries should provide about one year of service. However, when the
batteries become drained, “BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AAA batteries, You have approximately 1
minute to change the batteries and keep thermostat’s clock and program settings. Once
the batteries have become too low to ensure proper operation, your system will be
turned off, and the display will be cleared except for “BATT” flashing on the LCD display.
CAUTION:
Once only the “BATT” only display occurs, the thermostat is shut down, and
your system will no longer operate. In this condition, there is no temperature
control of your dwelling.
NOTE: The backlight will not function when the
thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30 days, we
recommend that you replace the old batteries with new alkaline batteries prior to
leaving.
INSTALLATION
What You Need
This thermostat includes two #8 slotted screws and two wall anchors for mounting. To
install your thermostat, you should have the following tools and materials.
■
Slotted Screwdriver(s)
■
Small Philips screwdriver
■
Hammer
■
Electric drill and 3/16” bit
■
Two1.5V (AAA) size alkaline batteries (included)
CAUTION:
To prevent electrical shock and/or equipment dam- damage, age, disconnect
electric power to system at main fuse or circuit breaker box until installation is
complete.
Before removing wires from old thermostat's switching sub base, label each wire with the
terminal designation it was removed from.
1. Shut off electricity at the main fuse box until installation is complete. Ensure that
electrical power is disconnected.
2. Remove Old Thermostat: A standard heat/cool thermostat consists of three basic
parts:
a. The cover, which may be either a snap-on or hinge type.
b. The base, which is removed by loosening all captive screws.
c. The switching sub base, which is removed by unscrewing the mounting screws that
hold it on the wall or suitable plate.
3. Remove the front cover of the old thermostat. With wires still attached, remove wall
plate from the wall. If the old thermostat has a wall mounting plate, remove the
thermostat and the wall mounting plate as an assembly.
4. Identify each wire attached to the old thermostat.
5. Disconnect the wires from the old thermostat one at a time. DO NOT LET WIRES
FALL BACK INTO THE WALL.
6. Install new thermostat using the following procedures.
WARNING
Do not use it on circuits exceeding specified voltage. Higher voltage will damage
control and could cause shock or fire hazard. Do not short out terminals on gas
valve or primary control to test. Short or incorrect wiring will damage thermostat
and could cause personal injury and/or property damage.
Selector Switches
Electric/Gas Switch (Fan Option)
Figure 1. Electric/Gas Switch (Fan Option)
This thermostat is configured from the factory to operate a heat/ cool, fossil fuel (gas, oil,
etc.), forced air system. It is configured correctly for any system that DOES NOT require
the thermostat to energize the fan on a call for heat. If you system is an electric heat or
heat-pump system that requires the thermostat to turn on the fan on a call for heat,
locate the ELEC/GAS switch on the back of the thermostat (see fig. 1) and switch it to
the ELEC position. This will allow the thermostat to energize the fan immediately on a
call for heat. If you are unsure if the heating/ cooling system requires the thermostat to
control the fan, contact a qualified heating and air conditioning service person. When the
thermostat is configured for Heat Pump, the thermostat will always power the circulator
fan on a call for heat in the HEAT mode. The ELEC/GAS switch must be set to match the
type of Auxiliary heat your system uses for proper operation in the EMER mode.
All wiring diagrams are for typical systems only. Refer to equipment manufacturers’
instructions for specific system wiring information.
Attach Thermostat Base to Wall
1. Remove the packing material from the thermostat. Gently pull the cover straight off the
base. Forcing or prying on the thermostat will cause damage to the unit.
2. Connect wires beneath terminal screws on base using appropriate wiring schematic
(see figs. 2 through 4).
3. Place base over hole in wall and mark mounting hole locations on wall using base as
a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 1, using two mounting screws. Place a
level against bottom of base, adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.) If you are using existing
mounting holes, or if holes drilled are too large and do not allow you to tighten base
snugly, use plastic screw anchors to secure sub base.
6. Push excess wire into wall and plug hole with a fireresistant material (such as
fiberglass insulation) to prevent drafts from affecting thermostat operation.

Heat Pump Terminal Outputs
Refer to equipment manufacturers' instructions for specific system wiring information.
You can configure the thermostat for use with the following heat pump system types:
HEAT PUMP TYPE 1 1. Single stage compressor system; gas or electric backup. This
thermostat is designed to operate a single-transformer system. If you have a
two-transformer system, cut and tape off one transformer. If transformer safety circuits
are in only one of the systems, remove the transformer of the system with NO safety
circuits. If required, replace remaining transformer with a 75VA Class II transformer. After
disconnecting one transformer, this two must be jumped together.
Use the terminal output information below to help you wire the thermostat properly for
your heat pump system. After wiring, see CONFIGURATION section for proper
thermostat configuration.
