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 11). 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 11). When the delay time has elapsed, the "HEAT" blower speed
terminal is de-energized.
