INTRODUCTION

Bryant’s 7-day, 5/2-day, 1-day programmable and non-programmable Preferred Series Thermidistat 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 located near the equipment and a two-wire connection is used between the Display Module and the Equipment Control Module. Single-piece installation requires more wiring and results in a higher profile. The Preferred Series Thermidistat has no need for batteries to store user-configured settings in memory. During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Bryant’s proven line of thermostats; it provides separate setpoints for heating and cooling in addition to humidification and dehumidification.

In the Preferred Series Thermidistat Control’s programmable configuration, different heating and cooling setpoints and times are programmable for 4 periods per day or 2 periods per day. Programming can be done for 7 days per week, 5/2 days per week, or 1 day. The programmable Thermidistat Control can also be user configured as a non-programmable Thermidistat Control. When operating as non-programmable, the Thermidistat Control will still have both temperature and humidity control.

The non-programmable Thermidistat Control features Touch ’N’ Got settings for quick and easy temperature change without complicated programming schedules. The non-programmable Thermidistat Control will still have both temperature and humidity control. And, its Touch ’N’ Go technology enables the user to switch between three different user-configurable settings through intuitive buttons located just below the display.
