When parts are ordered, MODEL NUMBER, SERIAL

not covered under warranty.
Section 4
1. With proper voltages observed thus far and modu-
lator 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 components.
