Line Voltage Connections

on the anticipator setting.

 

1.Connect 120 VAC power wire to the line voltage leads located behind the front con- trol panel.

2.Route the incoming 120 VAC power wire through the right side jacket panel.

3.Use the wire nuts provided to ensure a tight and secure connection.

4.The unit is provided with a service switch, check local code requirements for compli- ance.

NOTICE

If local electrical codes or conditions require an additional service switch, the installer must provide and install a fused disconnect or 15 amp (minimum) service switch.

Thermostat Wiring

1.Connect room thermostat or the end switch (isolated contact only) of a relay control panel to the Room Thermostat Snap-set located on the rear jacket panel.

2.Remove the snap-set cover and connect the thermostat wiring to terminals C and 1 per Figure 32.

3.For proper operation install the room ther- mostat on an inside wall away from influ- ences of heat and cold, i.e. water pipes,

Outdoor Temperature Limit

1.The PERFORMANCE PLUS may operate with a variable primary operating tempera- ture using an outdoor reset control provid- ed by the installer.

2.Remove the factory jumper across termi- nals 9 and 10 of the wiring terminal. See pages 41 and 42. Connect the outdoor limit control to those terminals.

3.Set the operating limits of the outdoor limit control as follows:

-Maximum operating temperature of 180ºF.

Minimum operating temperature of 150ºF.

4.Set the primary thermostat to the highest possible setting.
