1. With proper voltages observed thus far and modulator
responding correctly, wire the system (see Figure 1),
except have TS144 connected in place of jumper. Set
A1044 MIN temperature selector at least 10°F above
outdoor temperature. Set A1044 MAX temperature
selector at mid-range. Heater is now under control
by TS144 Discharge Air Monitor.
2. Turn Test-Potentiometer to maximum resistance.
Delivered air temperature should be per A1044 MAX
temperature setting. Turn Test-Potentiometer to
minimum resistance. Delivered air temperature
should be per A1044 MIN temperature setting. If
proper delivered air temperatures are observed, the
problem is identified with the space temperature
sensing and/or temperature selecting components and
circuits. See Troubleshooting Guide. If proper
delivered air temperatures are not observed, check
calibration. See Troubleshooting Guide.
Section 5
1. After test, remove all test equipment and reconnect all
