Dual Unit Control
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).
