Mount Wall Thermostat and Connect Thermostat

Wires

Determine the type of thermostat needed for unit application and
follow instructions in the appropriate section below.

ROBERTSHAW AIR CONDITIONING THERMOSTAT

1. Remove cover (friction fit) from thermostat body by grip-

ping at top and bottom and lifting from subbase. Use
extreme care not to damage working parts.

2. Remove subbase from thermostat body by loosening cap-

tive screws.

3. Hold subbase level against wall in final thermostat location.

Mark wall with a pencil where screws will attach subbase to
wall. Use designated subbase mounting holes only.

4. Set subbase aside and drill mounting holes in wall with

3/32-in. drill bit.

5. Route thermostat wires from hole in wall through opening

in center of subbase.

6. Attach thermostat subbase to wall using mounting screws

and predrilled holes in wall.

NOTE:

Make sure white wire on thermostat subbase is connected

to A2 terminal.

7. Strip approximately 1/2-in. of insulation off end of each

wire. Connect thermostat wires to appropriate thermostat
screw terminals on subbase. (See Fig. 18.)

8. Push excess wire back into wall. Seal hole in wall to prevent

drafts.

9. Mount thermostat body on subbase with captive screws.

10. Set heat anticipator indicator (located in upper left corner of

thermostat body) to appropriate value based on the heater
size for unit being installed. (See Table 6.)

11. Install thermostat cover. Carefully align "D" shaped dial

shaft with matching shaped hole in hub of setting dial, then
press cover carefully on thermostat body.

12. Set outdoor thermostat to 50°F.

NOTE:

Refer to Installation Instructions packaged with thermo-

stat for additional information.

(PROGRAMMABLE AND NON-PROGRAMMABLE)

1. Open thermostat rear door (mounting base) to expose

mounting holes. The base can be removed to simplify
mounting. Snap apart carefully at hinge to separate mount-
ing base from remainder of thermostat.

2. Route thermostat wires through large hole in mounting

base.

3. Level mounting base against wall and mark wall through 2

mounting holes.

4. Drill two 3/16-in. mounting holes in wall where marked.

5. Secure mounting base to wall with 2 screws and anchors

provided, making sure all wires extend through mounting
base.

6. Adjust wire length and routing to allow proper closure of

thermostat. Strip each wire end no more than 1/4-in. to
prevent adjacent wires from shorting together. Match and
connect equipment lead wire to correct terminals of the
thermostat connector. (See Fig. 19 and 20.)

NOTE:

All TSTAT models have no batteries and are not "power

stealing." They do require 24 vac (R and C terminals) to be
connected for proper operation. Thermostat will not operate
without these 2 connections.

7. Push excess wiring into wall. Seal hole in wall to prevent

drafts.

8. Snap hinge back together.

9. Turn on power to unit.

10. Reconfigure thermostat to energize fan (G) terminal

with call for heat (W).

Since this is a self-contained unit, there is no furnace or fan
coil to energize the blower when electric heat is initiated.
The thermostat MUST be reconfigured to start blower when
electric heat is selected (G is energized whenever W is
energized).

a. Non-Programmable Model

(1.) Enter thermostat configuration mode by pressing

and holding FAN button for approximately 10 sec.
The room temperature disappears and display
should read "1-." Thermostat is now in configura-
tion mode.
NOTE: If FAN button is pressed again or if no
button is pressed for 60 sec, thermostat will exit
configuration mode and return to normal operation.
To re-enter configuration mode, the FAN button
must be pressed and held for 10 sec again.

(2.) Use up and down buttons until thermostat display

reads "5-."

(3.) Press MODE button once to display current selec-

tion of ON or OFF. Factory default is OFF.

(4.) Use the up or down button to change from OFF to

ON.

(5.) Press FAN button to exit configuration mode.

NOTE:

Refer to electronic thermostat Installation Instructions for

more information if needed.
