4500 Thermostat Installation Instructions You will not be able to adjust room temperature by phone when the 4500 is bypassed. There are several uses for the BYPASS switch function: • Allows the user to go back to their pre-existing thermostat at any time. • Allows heating/air conditioning service people to bypass the 4500 during HVAC servicing and maintenance. The 4500 is out of the HVAC control circuit when bypassed.

4500 Thermostat Installation Instructions While installation of the 4500 is possible without the services of a HVAC contractor, some installers will prefer to have an HVAC contractor connect the 4500 to the HVAC system and test its operation. This is recommended if you do not have HVAC experience. In cases where you prefer to do the entire installation, it is suggested that the HVAC contractor be contacted for information on the type of heating system and the amount of “span” (i.e.
Section 3. Installing the 4500 Thermostat Sometimes, R and Rc are jumpered together at the premises thermostat and are connected to the HVAC system with a single common wire. This is the case if both heating and air conditioning are controlled by the same control system. The remaining three wires connect the thermostat to the heating, cooling and fan control loop inputs of the HVAC system.
4500 Thermostat Installation Instructions If you are installing the 4500 in a heat only system, the setup will look like Figure 4 below. 4286 PHONE MODULE R R 4500 THERMOSTAT HVAC System 6 8 5 PREMISES THERMOSTAT 3 IN OUT G W Heat (W) Heat (W) Fan (G) Fan (G) Figure 4. 4500 Thermostat with Heating System Only Some heating systems, such as the forced-air type, have a fan (connections are shown). Other heat-only systems may not include a fan, in which case the fan connections are not used.
Section 3. Installing the 4500 Thermostat When installing the 4500 thermostat, refer to the Summary of Connections at the back of this manual. This diagram depicts the 4500's terminal strip and shows exactly how the thermostat must be wired. The heating/cooling system and thermostat you are working on may not have all the connections shown. All heating systems have R and W connections. Heating systems with a fan control have the G connection.
4500 Thermostat Installation Instructions 5. Connect the tagged wires removed in step 4 from the HVAC system to the applicable terminals of the 4500. Refer to the following table for proper connection information. Table 1 Lead from HVAC system Terminal on 4500 Fan (green) (G) 8 Cool (yellow) (Y) 7 Heat (white) (W) 6 6. Connect a wire to each of the vacant terminals on the premises thermostat that you noted in step 4 above, and make a run from those terminals to the 4500.
Section 3. Installing the 4500 Thermostat 9. Connect the 4500 to the 4286 phone module using the supplied keypad type cable.
4500 Thermostat Installation Instructions 10. Once the 4500 is mounted, you need to set its DIP switch and 3-pin fan control jumper. These procedures are described below. Setting the DIP Switch The 4500 includes a DIP switch for setting the address of the thermostat. The 4286 phone access module can include up to 2 thermostats per system. These are referred to as thermostats 1 and 2. Set thermostat #1 DIP switch to address 01.
Section 3. Installing the 4500 Thermostat Setting the Fan Control Pins The three fan control pins in the center of the 4500 are used to control the operation of the HVAC system’s fan. Using the jumper provided, you can select whether or not the system’s fan should turn on with cooling and heating, or turn on only with cooling. The operation of the fan depends upon which two pins the jumper is installed on. If you want the fan to turn on with cooling only, place the jumper provided between pins 2 and 3.

4500 Thermostat Installation Instructions 5. Check the heat mode operation of the premises thermostat by varying its set point and verifying that the heating system turns on and off. 6. If the 4500 thermostat will control an air conditioning system, set the 4500 front panel slide switches to ACTIVE and COOL. Set the premises thermostat into its cool mode as well. If only heating will be controlled, skip to step 9. 7. Set the premises thermostat 10 degrees below the present room temperature.
Section 5. Testing the 4500 With the 4286 Phone Module 2. Obtain phone access from the phone module. Enter the 2-digit phone code. Enter the 4-digit system code if prompted. 3. Press # 99 on the phone keypad after the complete status announcement. 4. The 4286 will announce: “Thermostat Mode.” The temperature setting for thermostat #1 will follow. You can change its set point using menu selection 1 below. If thermostat #1 is in BYPASS or CHECK, that status will be announced instead of the set point.
4500 Thermostat Installation Instructions “For set-back on/off, enter 3.” Turning off set-back will result in it remaining disabled while armed away, until the next time the system is disarmed. This feature allows the user to turn off the set-back before returning home, so that the premises will have time to return to a comfortable at-home temperature. It also allows the user to turn off set-back before leaving home, when they plan to be away only a short time.

4500 Thermostat Installation Instructions 4500 or premises thermostat fails to control the HVAC system. 1. Check set points in 4500 and premises thermostat to ensure they are set properly. 2. If BYPASS of 4500 via its front panel switch causes existing thermostat to work properly, then problem is in the 4500 wiring or within the 4500 itself. If the existing thermostat does not work, check its wiring and battery, if any. 3. Check wiring connections. Refer to Summary of Connections diagram.
