2. Use vibration isolators (flex connectors) on zone dampers and duct work to minimize noise. 3. Place dampers away from areas that may be noise sensitive. 4. TXV is required in air conditioning and heat pump applica- tions. 5. Use separate isolated transformer to supply power to Comfort Zone System (50 va minimum, class 2, field supplied). 6. Load[...]

Before insulating the duct work, check for proper damper opera- tion. Apply the 24vac between COM and OPN to open the damper and COM and CLS to close the damper. (See Fig. 7.) The damper will modulate counter-clockwise to open and clockwise to close. If in an emergency it becomes necessary to force a damper open, manually press in the red quick bla[...]

2. Secure flexible duct to zone damper using SMACNA or other approved method. 3. Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator. 4. Insulate damper using 1-1/2-in. to 2-in. insulation. (Check your local codes.) NOTE: All zone dampers and duct work must be properly supporte[...]

5. Insert 2-conductor wiring through 1 of pre-drilled holes in side of back plate. 6. Connect sensor to 2-wire conductor using provided wire nuts. (See Fig. 16 for connection to Comfort Zone Center.) Step 7—Install Dx Coil Sensor The Dx coil temperature sensor is recommended for use in heat pump with fan coil applications only. The sensor should [...]

Changing the base temperatures will change the Comfort Temperature Setpoints used in the system schedules. Always set the Base Temperatures prior to programming the system schedules. Comfort Zone also uses a minimum temperature and a maximum temperature for comfort setpoints. The minimum and maximum temperatures are the same for all 4 zones. The Ma[...]

If Fan Switch on 4 zone controller is set to ON instead of Auto, then system fan will run continuously. Any time Comfort Zone is operating fan, it will be in active control of system. NOTE: If Auto Fan Off For Heating option (rotary switch position T-9) is ON, and Fan Switch on the 4 zone controller is ON, Comfort Zone will operate fan full time. O[...]

heater. The electric strip heat is much more expensive to operate when comparing cost per unit of heat. Because auxiliary stages of heating tend to be more expensive to operate, Comfort Zone attempts to keep number of stages at a minimum. CONFIGURATION OPTIONS FOR EQUIPMENT OPERATION Comfort Zone has several configurable options which allow it to c[...]

NOTE: Comfort Zone uses a 3-minute timer to delay start of second-stage (heating or cooling). This timer is started whenever first-stage heating or cooling is energized. This delay cannot be overridden or disabled. STAGE CONTROL DURING EQUIPMENT OPERATION As shown earlier, Comfort Zone has 6 configurable options which help govern equipment operatio[...]

then temperature at which first stage will be shut down will be offset 5°F above limit value (110°F to 114°F). If limit temperature is between 110°F and 155°F, then temperature at which first stage will shut down will be offset 20°F above limit value (130°F to 175°F). For Cooling modes the temperature is fixed at 50°F (10°C) for starting [...]

If a value of 105 to 110 is selected (second-stage heating is turned off at this value) then the first-stage high temperature trip limit is the programmed value plus 5°F (first-stage is turned off). If a value of 111 to 155 is selected (second-stage heating is turned off) then the first-stage high temperature trip limit is the programmed value plu[...]

7. Write down on a piece of paper AND GIVE TO THE OWNER a list showing what rooms are controlled by what dampers, and their corresponding zone numbers. Keep list for your future use. 8. Instruct owner to turn cool switch OFF in the fall, and turn it ON in the spring. 9. Make sure emergency heat switch is in the OFF position. If a gas furnace is use[...]

Cool Switch OFF —Cooling will not come on. AUTO —Cooling will come on when any zone is more than 1.5°F above desired cool setpoint. Fan Switch ON —Fan will stay on continuously (recommended). AUTO —Fan will come on only when heating or cooling is required. Emergency Heat Switch (Heat Pump Systems only) OFF —Electric strip heat will not c[...]

Press ADVANCE TIME/DAY button until desired start time is displayed. 6. Adjust setpoints. Adjust setpoints using up and down buttons until desired temperatures for the selected time period appear in display. These setpoints will be used during the time period currently displayed in clock window. 7. Complete time period programming. Repeat 4 through[...]

OUTSIDE AIR TEMPERATURE SENSOR The Outside Air Temperature Sensor must be used whenever an Outside Air Damper is installed. An Outside Air Temperature Sensor must also be used for dual fuel applications.
