1. 5 minutes delay between start to start of the compressor ( anti short cycle delay).
2. 2 minutes delay between stop to start of the same compressor.
3. Compressor sequences as follows:
COOL1 ON AT TEMP SETPOINT + COOL SETBACK TEMP + TEMP DEADBANB
COOL2 ON AT TEMP SETPOINT + COOL SETBACK TEMP + TEMP DEADBANB + .3°F (IF EXISTS)
COOL2 OFF AT TEMP SETPOINT + COOL SETBACK TEMP + TEMP DEADBAND (IF EXISTS)
COOL1 OFF AT TEMP SETPOINT + COOL SETBACK TEMP
SETBACK HEATING LOGIC
When a SETBACK/UP time-of-day schedule is in effect and the Mini-DAP is operating in the
“unoccupied” mode, the effective heating setpoint will be adjusted downward
by the amount
specified in menu #17.
1. 1 minute delay between stop to start of the reheat. Reheat will be overrided by humidification.
2. Heating sequences as follows:
HEAT ON AT TEMP SETPOINT - HEAT SETBACK TEMP – TEMP DEADBAND - .3°F
HEAT OFF AT TEMP SETPOINT – HEAT SETBACK TEMP
SETBACK HUMIDIFICATION LOGIC
When a SETBACK/UP time-of-day schedule is in effect and the Mini-DAP is operating in the
“unoccupied” mode, the effective setpoint for humidification will be adjusted downward
by the
amount specified in menu #19.
1. Heat will be overrided by humidification unless menu #46 is set for “COMFORT”.
2. 1 minute delay between stop to start of humidification.
3. 5 minutes delay between humidification and dehumidification.
4. Humidification sequences as follows:
HUMIDIFIER ON AT HUMIDITY SETPOINT – HUMIDITY SETBACK – HUMIDITY DEADBAND
HUMIDIFIER OFF AT HUMIDITY SETPOINT – HUMIDITY SETBACK – 1%
SETUP DEHUMIDIFICATION LOGIC
When a SETBACK/UP time-of-day schedule is in effect and the Mini-DAP is operating in the
“unoccupied” mode, the effective setpoint for dehumidification will be adjusted upward
by the
amount specified in menu #18.
1. Dehumidification is not governed by the adjustment rate but the operation will not violate compressor
short cycle times
2. Heating is used to reheat the overcooled and dehumified air but heating short cycle times will not be
violated. Also if heating comes on and return air temperature is still below temperature setpoint minus
temperature deadband minus 2°F, the dehumidification cooling will be inhibited until the temperature
goes back to the temperature setpoint.
3. When reheat comes on, the second stage of cooling will go off if it exists.
4. 1 minute delay between stop to start of the dehumidification.
5. Dehumidification compressor staging sequence:
COOL1 ON AT HUMIDITY SETPOINT + HUMIDITY SETBACK + HUMIDITY DEADBAND
COOL2 ON AT HUMIDITY SETPOINT + HUMIDITY SETBACK + HUMIDITY DEADBAND + 1%
COOL2 OFF AT HUMIDITY SETPOINT + HUMIDITY SETBACK + 1%
COOL1 OFF AT HUMIDITY SETPOINT + HUMIDITY SETBACK
