TASKMASTER SERIES

T5100, T5102, T5122, TC5102 AND TC5103 Built-in Thermostat Kits for Field installation in the 5100

Series Unit Heaters.

T5100 provides SPST line voltage control for single phase heaters up to 277V, 25a.

Pilot duty control (24-277 volt) for contactor equipped heaters.

T5102 provides double pole line voltage control breaking all ungrounded conductors for single phase

heaters up to 277V, 25 amperes.

Two pole line cycling control for 3 phase heaters up to 240 volts, 25 amps but does not break all

ungrounded conductors on 3 phase applications.

T5122 provides two stage low voltage (24V) control for two stage heaters. Two separate circuits are

controlled by the same sensing element. Switches controlling these circuits are calibrated to make

or break in sequence.

TC5102 is a thermostat and relay for use with 480 & 600 volt heaters to control the fan motor. It provides for

sensing of heat accumulation (strat-stat) near the ceiling and switches the fan motor on to recirculate

and recover this heat.

TC5103 provides control of the fan motor on 208, 240 & 277 volt heaters to recover and recirculate the

statified heat accumulated near the ceiling.

Please read each installation instruction carefully before beginning installation.

INSTALLATION INSTRUCTIONS T5100, T5102, T5122

1.) CAUTION:

To avoid possible electric shock, turn heater OFF at distribution panel. On heaters equipped with a

disconnect switch, rotate switch to the OFF position.

2.) Unlock the 2 screws on the control panel door and let door swing down. Some models have an

additional center door catch. Squeeze catch to open.

3.) Remove 1/2 (13mm) diameter thermostat bulb exit knockout from back of heater, Fig. 1. Feed

thermostat bulb and capillary tube thru knockout.

CAUTION: Keep capillary tubing away from internal electrical components.

4.) Remove 2 small thermostat bulb clip knockouts on the rear of the heater, see Fig. 1. Insert 2 bulb clips

(supplied). Snap thermostat bulb into clips.

5.) Remove the three stat mounting knockouts from side of control compartment: (1) 9/16 & (2) 3/16. Remove

backing from label (supplied). Align label with thermostat shaft hole and position as in Fig. 1. Press label

on heater side as shown.

6.) Note orientation of leg on thermostat bracket (see Fig. 1). Position only as shown. Install thermostat with

the (2) number 8 mounting screws provided.
