3 INTRODUCTION Bryant’s 7--day, 5/2--day, 1--day programmable and non--programmablePreferred t Series Thermostat Control is a wall--mounted, low--voltage control which combines temperature and humidity control in either a single unit or a two--piece unit. In two--piece configuration, the relays are ...
Page 4 - INSTALLATION CONSIDERATIONS; Power
4 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 properoperation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper. See...
