Location
For accurate temperature detection, thermostats should be mounted
on an inside wall (46 cm or 18” from any outside wall) in a frequently
occupied area with freely circulating air. It should be approximately
1.5 m (5’) above floor. Avoid direct sunlight, radiant heat from appli-
ances, air conditioner grills, stairwells, water pipes, warm air stacks,
and sources of electrical interference such as arcing relay contacts.
Installation
1. Lift thermostat cover and insert flat blade screwdriver or coin,
approx. 3 mm (1/8”) into the slot located in bottom centre of case.
Twist ¼ turn to pop the thermostat loose from its backplate.
2. Swing thermostat from bottom (hinge at top), raise from back-
plate, and remove from hinge tabs. Place the backplate’s rectan-
gular opening over control panel wires protruding from the wall.
Use backplate as a template to mark location of two mounting
holes.
3. Use supplied anchors and screws for mounting. Drill two 5 mm
(3/16”) mounting holes. Tap nylon anchors flush to wall and fas-
ten backplate with screws.
4. Connect control panel wires to thermostat as shown in wiring
diagram. Push any slack wire back into wall. Dress remaining
wires to make them flush with backplate. Seal or stuff access
hole to prevent drafts through wall from affecting thermostat’s
performance.
5. Install optional setback, indoor/outdoor remote sensors, if used.
6. Replace thermostat to backplate by inserting its top into back-
plate’s hinge tabs, swinging downward and snapping back into
place.

EMS-100 Thermostat
OPERATING INSTRUCTIONS
The thermostat normally displays room temperature, mode of opera-
tion (i.e. Day or Night), and whether Cooling or Heating is currently
on. The six buttons on the front of the unit allow complete control of
the thermostat. The user may specify different Heating and Cooling
setpoints, and change them easily by pushing a button. Temperature
can be displayed in either C or F. The thermostat also allows the
user to select either continuous fan operation, or fan operation only
during operation of the heating/cooling device(s).
