The InteleCool

®

 Dual Unit Control is designed to control two InteleCools in a “lead/lag” fashion. The 

control contains an electronic timer for switching the operating sequence of two units on a one-, two-, 

four-, or eight-day basis. It also contains a two-stage heat/two-stage cool thermostat with individual 

heat and cool set points. Light emitting diodes (LEDs) indicate Lead Unit 1 or 2 and power from 

Unit 1 or 2. The schedule for lead/lag switchover is adjustable by moving jumpers on the printed cir-

cuit board. A jumper is also used to change lead and lag unit before a scheduled changeover (if neces-

sary for servicing).

Consult the Tele2 user manual for installation instructions.
