Final Control Settings
When all start-up procedures have been completed, set the
controls and program the MicroTech controller for normal
operation. Use the following list as a guide; some items may
not apply to your unit.
1. Turn system switch S1 to “on.”
2. Turn gas furnace switch S3 to “auto” or turn electric heat
switch HS1 to “on.”
3. Set the electromechanical (Honeywell H205) enthalpy
control (OAE) as required (A, B, C, or D). Set the solid-
state (Honeywell H705/C7400) enthalpy control (OAE/
RAE) past “D”.
4. Set the heating and cooling control parameters as re-
quired (keypad menus 12 through 14).
5. Set the high ambient heating lockout set point, “Max
OAT=” (keypad menu item 14B), as required.
6. Set the alarm limits as required (keypad menu 15).
7. Set the unoccupied heating and cooling set points as
required (keypad menu 17).
8. Set the duct static pressure control parameters as
required (keypad menu 18).
9. Set the fan tracking or building static pressure control
parameters as required (keypad menu 19).
10. Set the economizer control parameters as required
(keypad menu 21).
11. Set the dirty filter set points as required (keypad menu
22). If a Remote Monitor Panel is being used, set the set
points on dirty filter switches PC5 (filter) and PC6 (op-
tional final filter). The maximum recommended settings
are 0.5" w.c. (125 kPa) for throwaway-type filters, 1.0"
w.c. (249 kPa) for 30% pleat-type filters, and 1.5" w.c.
(374 kPa) for cartridge-type filters.
12. Set the control timers as required (keypad menu 23).
13. Set the date and time (keypad menu 24).
14. Set the operating schedule as required (keypad menus
25 and 26).
15. Place the unit into the Calibrate mode by selecting it
from keypad menu 11, “Control Mode.” Calibrate will
automatically zero all pressure sensors and calibrate
any actuator feedback pots connected to the MicroTech
controller. When Calibrate is finished, set the control
mode as required.
Maintaining control parameter records
It is recommended that the MicroTech controller’s set points
and parameters be recorded and saved for future reference.
If the Microprocessor Control Board ever requires replace-
ment, this record will facilitate entering the unit’s proper data.
Using the following table, record the data directly on the
pages (with a pencil) or on photocopies of the pages. Keep
this record in a safe place and remember to update it whenever
further changes are made.
