HEAVY DUTY THERMOSTATS

The T6051 Heavy Duty Thermostat may be used in
heating only systems, cooling only systems, combination
heat-cool systems (system changeover means must be

provided), or as a series 60 controller for valves or motors.

The T6052A is for two stage heating or two stage

cooling systems. The T6052B is for one stage heating­cooling systems with automatic changeover.

The Q651 Subbase may be used with the T6051 and
T6052B thermostats to provide system witching at the
thermostat location. Refer to applicable specification
sheet for additional information.

INSTALLATION

---

--------------------------------------—

LOCATION

Locate the thermostat about five feet above the floor

on an inside wall where it will be affected only by the
average temperature of the room. The T6051A may be
mounted either vertically or horizontally.

If using a 0651 Subbase, refer to the instructions

packed with the subbase.

MOUNTING

1. If mounting horizontally, coverplate must be
changed. To remove vertical coverplate, bend four
corner tabs to outside and oush out on cover. Place
horizontal coverplate on cover frame and bend four
corner tabs to inside. (See Fig. 1).

2. Mount the 2 by 4 inch outlet box either vertically

or horizontally, as desired.

3. Run conduit between the outlet box, power source,
and the unit being controlled. Leave about six inches of
wire in the box for connections. (Refer to the WIRING
section for the number of wires required.)

4. Place the mounting plate on the outlet box either
vertically or horizontally. Insert the two furnished
mounting screws, leaving them loose enough to move
the mounting plate for leveling. See Fig. 2.

5. Level the mounting plate and tighten the mounting
screws. (See Fig. 2.)

6. Connect the heating and/or cooling system wires
or the Series 60 equipment wires to the back terminals
of the thermostat. See Figs. 3—10.

7. When wiring is complete, secure the fiber insulator
by snapping the holes in the flap over the switch rivet
heads. When the normally open terminal is used, clip the
flap to allow it to pass around the wire.

8. Hang thermostat on mounting plate tabs, see

Fig. 2.

9. Take socket-head cover mounting screw (furnished)
and insert it in tab at bottom of base. Do not tighten.

Replace cover.

10. Insert set point knob into socket-head screw and

tighten. This fastens cover and thermostat to the mount
ing plate previously attached to outlet box. Remove knob.

WIRING

CAUTION

Disconnect power supply before making wiring
connections to prevent electrical shock and
equipment damage.

All wiring must agree with local electrical codes and

ordinances. Refer to the wiring diagrams below, instruc
tions packed with the subbase, and heating and/or cooling
equipment manufacturer's instructions.
