2 INTRODUCTION Bryant’s 7 − day, 5/2 − day, 1 − day programmable and non − programmable Preferred Series Thermostat Control is a wall − mounted, low − voltage temperature control in either a single unit or a two − piece unit. In two − piece configuration, the relays are located near the equipment an...

Page 5 - INSTALLATION CONSIDERATIONS; Power

3 INSTALLATION CONSIDERATIONS Power This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low − voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper. S...
