START-UP PROCEDURE AND ADJUSTMENT

7.Select the heating speed for your model from the heating speed chart in the Specification Sheet. The adjust setting (already established by the cooling speed selection) determines which set of speeds are available. The selected speed must provide a temperature rise within the rise range listed with the particular model.

Example: The *MVC80704BX is set for 990 CFM on cooling, the “ADJUST” is set to “+” (plus). The four heating speeds available are “A Plus”, “B Plus”, “C Plus”, and “D Plus”. “A Plus” has a rise of 38°F for both stages which is within the 20-50°F rise range for the *MVC80704BX . This setting will keep electrical consumption to a minimum. Set the “Heat” speed DIP switches to “A”.

8.Select the desired “heating” speed tap by positioning switches 7 and 8 appropriately. Refer to figure above. Verify CFM by noting the number displayed on the dual 7-segment LED display.

In general lower heating speeds will: reduce electrical consump- tion, lower operating sound levels of the blower, and increase the outlet air temperature delivered to the home. The speeds available allow the blower performance to be optimized for the particular homeowner’s needs.

BLOWER HEAT OFF DELAY TIMINGS

The integrated control module provides a selectable heat off delay function. The heat off delay period may be set to 90, 120, 150, 180 seconds using the DIP switches or jumper provided on the control module. The delay is factory shipped at 150 seconds but may be changed to suit the installation require- ments and/or homeowner preference. Refer to the following fig- ures for switch positions and corresponding delay times.
