ATTENTION! This product does not contain mercury. How-
ever, this product may replace a unit which contains mercury.
Do not open mercury cells. If a cell becomes damaged, do
not touch any spilled mercury. Wearing non-absorbent gloves,
take up the spilled mercury and place into a container which
can be sealed. If a cell becomes damaged, the unit should be
discarded.

Mercury must not be discarded in household trash. When the
unit this product is replacing is to be discarded, place in a suit-
send product containing mercury.
Attach Thermostat Base to Wall
1. Remove the packing material from the thermostat. Gently
pull the body straight off the base. Forcing or prying on the
thermostat will cause damage to the unit.
MOUNTING AND WIRING

2. Connect wires beneath terminal screws on base using ap-
propriate wiring schematic (see fig. 2).
3. Place base over hole in wall and mark mounting hole loca-
tions on wall using base as a template.
WARNING
!
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
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.Adjust until level, and then tighten screws.
(Levelingisforappearanceonlyandwillnotaffectthermostat
operation.)Ifyouareusingexistingmountingholes,orifholes
drilled are too large and do not allow you to tighten base
snugly, use plastic screw anchors to secure subbase.
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.
Thermostat installation and all components of the
system shall conform to Class II circuits per the
NEC code.
6. Push excess wire into wall and plug hole with a fire-resistant
material(suchasfiberglassinsulation)topreventdraftsfrom
affecting thermostat operation.
Battery Location
Hydronic (Hot Water or Steam)
Heating Systems
This thermostat requires 2 “AAA” alkaline batteries to operate.
Thisthermostatissettooperateproperlywithaforced-airheating
system. If you have a hydronic heating system (a system that
heats with hot water or steam), you must set the thermostat to
operate properly with your system.
If
appears on the display, the batteries are low
and should be replaced with fresh “AAA” Energizer® alkaline
batteries.Thebatteriesarelocatedonthebackofthethermostat
body (see fig. 1).
The factory default setting is forced air heat. Clipping jumper
W905 on the circuit board will produce a longer heating cycle
whichisnormallyforhotwaterorsteam(hydronic)systems.Both
settings produce a very accurate temperature control and can
be set to your personal preference. As received, the thermostat
cycles the system just under 1°F.WithW905 clipped, the system
cycles at approximately 1.5°F.
