TYPE 1F57-312 LOW VOLTAGE
MULTI-STAGE THERMOSTAT
(2 Stage Heat, 2 Stage Cool)
(Fan Relay cycles on both heating & cooling)
These multi-stage heating-cooling thermostats provide low
voltage control of up to two stages of heating and two stages
of cooling. Switches on the Sub-Base provide convenient
selection of heating, cooling, and blower operation on cooling
air conditioning systems using electric heat where thermostat cycles the fan relay on both heating and cooling.
First stage Heat is equipped with an adjustable heat anticipator
while 2nd stage is non-anticipated. First stage Cooling is
equipped with cooling anticipation while the 2nd stage is not.
SELECTING THERMOSTAT LOCATION
The proper location of the room thermostat is most important
to insure that it will provide a comfortable home temperature.
Observe the following general rules when selecting a location:
1. Locate it about 5 ft. above the floor.
2. Install it on a partitioning wall, not on an outside wall.
3. Never expose it to direct light from lamps, sun, fireplaces,
etc.
4. Avoid locations close to doors that lead outside, windows,
or adjoining outside walls.
5. Avoid locations close to radiators, warm air registers, or in
the direct path of heat from them.
6. Make sure there are no pipes or duct work in that part of
the wall chosen for the thermostat location.
7. Never locate it in a room that is warmer or cooler than the
rest of the home, such as kitchen or hallway.
8. The living or dining room is normally a good location,
provided there is no cooking range or refrigerator on
opposite side of wall.
INSTALLATION
MOUNTING SCREWS
Attaching Sub-Base to Wall
1. Route wires from heating and cooling equipment to
thermostat location and pull wires through hole in wall so
that 6 in. of cable protrudes.
2. Pull wires through opening near center of sub-base and
connect wires beneath proper terminals screws as shown
under "wiring".
3. Push excess wire into wall or switch box and plug up hole
to prevent drafts from affecting thermostat operation.
4. Fasten sub-base loosely to wall in position shown in Fig. 1
using two mounting screws provided. Level sub-base by
placing spirit level on top of sub-base. Tighten mounting
screws to secure sub-base in level position.
Mounting Thermostat to Sub-Base
Step 1. Remove cover from thermostat by pulling it straight
outward.
Step 2. Attach thermostat base to sub-base, being sure that all
six screws are tightened snugly since they serve as

NOTE: Do not assembly cover to thermostat base until
heat anticipator has been set as described below.
HEATING ANTICIPATION
T h i s thermostat is equipped with an adjustable heat
anticipator on 1st stage of heating. The anitcipator may be
adjusted for current ratings from .15 to 1.0 Amp.
1. Check setting of adjustable heat anticipator and readjust if
necessary to comply with setting specified on installation
i n s t r u c t i o n s included with heating equipment being
installed.
2. Snap on thermostat cover and set thermostat to desired
setting.
Additional adjustments, if necessary, may be made as follows;
Heater cycles too long — Set adjustable heater to a slightly
lower dial setting (1/2 division). Heater cycles too short — Set adjustable heater to a slightly
higher dial setting (1/2 division).
