Heat Mode
When a call for heat ("W") is received from the thermostat, if the "Cool" mode is not already
active, the "T-T" terminal is energized and the blower on delay is started. The on-off pattern of
DIP switch SW2 (positions 1 and 2) select one of four blower on delay values (see Table 6).
When the delay time has elapsed, the "HEAT" blower speed is energized. The control remains
in steady heat mode until the thermostat is satisfied. When the call for heat signal is removed, the
"T-T" terminal is de-energized and the blower off delay is started. The on-off pattern of DIP
switch SW2 (positions 3 and 4) select one of four blower off delay values (see Table 8). When
the delay time has elapsed, the "HEAT" blower speed terminal is de-energized.
