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.
3 INST ALLA TION CONSIDERA TIONS Power This control is powered by 24V AC only . It requires 24V AC (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.
4 A07052 Fig. 1 − PCB Br eakout Jumper Models There are programmable and non − programmable models for all applications. They can be configured for AC or HP installations, allowing it to be used in place of all Bryant thermostats. Programmable thermostats may be configured as non − programmable if user desires.
5 dedicated sensor wires may be used for its connection. Details are provided in sensor instructions. Remote Indoor T emperatur e Sensor A remote temperature sensor may be used with the programmable h.
6 Wiring W ire length should be no more than 250 ft (76m). Use 22 A WG for normal wiring applications. Continuous wire lengths over 100 ft (30.5m) should use 20 A WG or larger . INST ALLA TION Carton contains the following components. See Fig. 2 for programmable models or Fig.

8 AC/HP Control should NOT be mounted: Close to a window , on an outside wall, or next to a door leading to the outside. Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature − radiating objects which could cause a false reading.
9 UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Improper wiring or installation may damage AC/HP Control. Check to make sure wiring is correct before proceeding with installation or turning on power .
10 Tw o − Piece Installation The following steps should be followed for the installation of the two − piece configuration. NOTE : The 2 − wire pigtail is not intended to support the weight of the User Interface. Do not hang the User Interface from the equipment Control Module screw terminals.

22 must be properly set by the installer . (Only those marked with an asterisk * below are available to the homeowner .) The homeowner configurations are described in the owner’ s manual. A special procedure allows entry into the configuration mode.
23 Option 18* — Backlight Configuration Option 19 — Dry Contact (programmable models only) Option 20 — Outdoor Air T emperature Offset Adjustment Option 21* — Keypad Lockout Option 24* — Pro.
24 WHILE IN CONFIGURA TION MODE The option number is displayed in the heat setpoint location and the configuration setting is displayed in the cool setpoint location. On the T6 − P AC/PHP (programmable) models, a box will surround the option number .
25 Defaults HP model defaults to HP . AC model defaults to AC. Option 02 — Clean Filter T imer Select hours of blower operation (heating, cooling, or fan) before CHECK FIL TER icon is displayed. With OF selected, icon will never come on, disabling this feature.
26 Sensor 1 Sensor 2 Sensor 3 Sensor 4 RRS SRTN A09130 Fig. 16 − Remote Room Sensor − Parallel W iring This selection determines which sensor the control will use for measuring room air temperature.
27 Option 07 — Zoning This selection should be set to On when the thermostat is to be used as part of a zoning system. It is assumed that the zoning equipment will take care of time guard and cycle timers. The minimum on time is still controlled by the thermostat.
28 C — Reversing valve output (O/W2/B) is energized when COOL mode is selected. Default is C. Option 1 1 — Deadband Setting Between Heat & Cool This option is not available on Heat Only and Cool Only systems. This selection is to allow the installer to choose how much differential exists between the heating and cooling setpoints.
29 On — Auto mode is available. OF — Auto mode is not available. Default is On. Option 16 — Maximum Cycles Per Hour This selection limits the number of cycles per hour that the thermostat allows the system to operate. Selections are 2, 4, 6. 2 — The heating and cooling outputs will be energized no more than 2 times per hour .
30 becomes brighter when a button is pressed. After 10 seconds of no button presses, the backlight will return to the dimmer level until another button press occurs.
31 1 — The user has access to modify setpoints, time of day . 2 — The user has access to change the setpoints only . 3 — The entire keypad is locked. When a button is pressed, the backlight will turn on but none of the operating parameters will be changed.
32 Option 22 — High Cool Latch T emperatur e (only available if outdoor sensor is pr esent) An outdoor sensor is required for high cool latch feature. This selection is only available when Option 1 is set to H2, A2, or h2 and when Option 7 (zoning) is set to OF (off).
33 When a cycle starts under a high heat latch, it will finish the heating cycle on high stage. On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all heating demands.
34 Option 27 — Maximum Heating Setpoint This selection allows the installer to configure the maximum heating setpoint. The range is based on the adjustable deadband value Option 1 1, such that the minimum of the range is 50 F/10 C and the maximum is 90 F/32 C minus the deadband.
35 “overrides” the programmed fan setting by pressing the fan button, the override selection will remain in ef fect until the next programmed period time.
36 2 — Thermostat will control the W1 and O/W2/B outputs. Default is 1. Option 33 — Single or T wo − Piece Installation This configuration allows the thermostat to compensate for the amount of heat generated by the thermostat electronics to allow more accurate sensing of the temperature sensor .
37 of f even if the user has the fan selection set to continuous fan. The fan output will be turned back on in this temperature range if the maximum capacity of auxiliary heat is on due to system demand (auxiliary heat on in response to a defrost signal shouldn’t cause the fan to turn back on).
38 SYSTEM ST AR T − UP AND CHECKOUT The AC/HP Control is designed with a built − in installer test capability . It allows easy operation of equipment without delays or setpoint adjustments to force heating or cooling. T o enable installer test mode, press and hold the fan button for 15 seconds.
39 TO TEST F AN Fan button switches F AN icon between AUT O and On. While On is displayed, G output will be energized, turning fan on. On some fan coils, fan continues to operate for 90 sec after G signal is removed. Final Settings Be sure to press DONE to exit installer setup mode.
40 If fixed temperatures are desired, use SCHEDULE button to turn on arrow icon next to HOLD. This will maintain setpoints, not allowing them to change with programmed schedule. The F AN button may be used to select between AUTO (fan on only with equipment) and On (fan on continuously) fan modes.
41 V acation (programmable models only) A vacation selection is available specifically for times where the home will not be occupied for an extended period. V acation mode has an automatic hold, meaning that setpoints are not affected by the programmed schedule.
42 Cycle Timer Based on the selection of 2, 4, or 6 cycles per hour, this timer is set to 30, 15, or 10 minutes. This much time must elapse from the start of one cycle before another cycle can start. It serves to impose the cycles per hour limits. It can be defeated for one cycle by simultaneously pressing the F AN and UP buttons.
43 Detect that defrost is in progress and energize the auxiliary heat to provide homeowner comfort during the defrost cycle Allow a defrost cycle to run to completion regardless of the system demand Thr ee − Minute Minimum on T ime In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes.
44 Emergency Heat Mode When AC/HP Control is configured as a heat pump and emer gency heat is selected, all Y signals are locked out, and W becomes ener gized upon a call for heat. Pr ogrammable Fan (pr ogrammable models only) The fan output can be programmed based on period of the day .
45 Relays This thermostat uses latching relays. When the thermostat loses power , the relays will remain in their last position until power is restored and all relays are reset to their correct position. Out of the box, the outputs may appear to be On when the thermostat is not powered.
46 temperature sensed by the working sensor every 10 seconds. The control will operate from the temperature sensed by the working sensor . E1 − If the Display Module and the Equipment Control Module cannot communicate via two − wire connection, an E1 will be displayed.
