Step 2—Wiring To prevent personal injury or possible equipment damage, disconnect the power supply before routing wire. All wiring must comply with local, state, and national codes. NOTE: Use No. 18 AWG color-coded, insulated (35°C min) wire. If thermostats are to be located more than 100 ft from the WeatherMaker Two-Zone Center as measured alon[...]

2. Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator. 3. Insulate damper using 1-1/2-in. to 2-in. insulation. (Check your local codes.) (See Fig. 7.) NOTE: All zone dampers and ductwork must be properly sup- ported according to local codes or SMACNA standards. NOTE: There sho[...]

Step 5—Install Barometric Bypass Damper NOTE: The barometric bypass damper is a critical part of the WeatherMaker Two-Zone System for control of minimum airflow and noise reduction. It is recommended that the bypass be installed. The bypass should be installed according to local codes and SMACNA standards. Be sure the bypass is properly supported[...]

In automatic changeover, the zoning system works on a first come first serve basis. If 1 zone is calling for heating and the other for cooling, the zone which sent its demand to the I/O center first will operate the equipment in that mode until that zone is satisfied. Step 5—Duct Temperature Optimizer (DTO) For Monitoring Leaving Air Temperature [...]

NOTE: An HP temperature sensor must be used with a heat pump application using electric strip heat. This is necessary in case the DTO is set to the Off position. Timeguard The WeatherMaker Two-Zone provides equipment protection with an internal 5-minute timeguard delay. This delay is present upon initial power up. There is also a 5-minute timeguard[...]

timer will start counting down 15, 14, 13...0 minutes. Once the timer expires the control will allow a new mode to restart the equipment. The internal time, as well as the cooling 5-minute timeguard can be cleared by using the comprotec override feature. CARE AND MAINTENANCE For continuing optimum performance and to minimize possible equipment fail[...]

TROUBLESHOOTING This section contains information to assist you in troubleshooting problems and errors associated with the WeatherMaker Two-Zone system. See Table 2. Step 1—System Diagram, Jumpers, and Switches NOTE: For correct control board operation, it must have either a sensor attached or a 10k resistor in place at the duct and HP inputs. 1 [...]

Table 3 shows a temperature/ohm/voltage relationship to help aid in troubleshooting the WeatherMaker Two-Zone System. This table will evaluate both the Duct/HP temperature sensor operation. Use a digital multimeter to perform the following: To verify a sensor is good, disconnect both leads from the I/O board and measure the resistance through the s[...]
