WATER-SOURCE HEAT PUMP (E) SEQUENCE FOR REFERENCE

WATER-SOURCE HEAT PUMP SEQUENCE OF OPERATION (HP-1 THRU HP-6).

1. GENERAL

A. EACH PUMP OPERATES IN ANY ONE OF FOUR MODELS: MORNING WARM UP, MORNING COOL DOWN, OCCUPIED, OR UNOCCUPIED. B. OCCUPIED AND UNOCCUPIED TIME OF DAY SCHEDULE FOR EACH HEAT PUMP IS PROVIDED.

2. OCCUPIED MODE

A. THE SUPPLY FAN OPERATES CONTINUOUSLY. B. TEMPERATURE CONTROL

a. THE COMPRESSOR OPERATES IN COOLING OR HEATING MODE AS NECESSARY TO MAINTAIN OCCUPIED ZONE TEMPERATURE SETPOINTS. b. ON A CALL FOR HEATING OR COOLING, A 30 SECOND TIME DELAY IS PROVIDED BEFORE COMPRESSOR ENABLEMENT TO ENSURE CONDENSER

WATER PUMP FLOW IS ESTABLISHED. C. DIRECT OUTSIDE AIR UNIT INTERBLOCK

a. THE DOAS UNIT ASSOCIATED WITH THE HEAT PUMP OPERATES ON A STAND-ALONE SCHEDULE. D. DAMPER CONTROL

a. HP-1: THE OUTSIDE AIR DAMPER IS FIXED POSITION AND WILL NOT BE CONTROLLED, VENTILATION TO BE PROVIDED WHEN ASSOCIATED DOAS IS ENABLED.

b. HP-2 THRU HP-6: THE OUTSIDE AIR DAMPER OPENS TO MINIMUM POSITION WHEN THE UNIT IS ENABLED IN OCCUPIED MODE. 3. UNOCCUPIED MODE

A. THE SUPPLY FNA IS OFF AND OUTSIDE AIR DAMPER CLOSED (IF APPLICABLE). B. THE ASSOCIATED DOAS UNIT IS ENABLED OR DISABLED ON A SEPARATE SCHEDULE. C. THE COMPRESSOR IS DISABLED.

D. IF THE ZONE TEMPERATURE FALLS BELOW THE UNOCCUPIED MODE HEATING SETPOINT, FOLLOW THE MORNING WARM UP SEQUENCE UNTIL ZONE TEMPERATURE IS 2 DEGREES FAHRENHEIT ABOVE UNOCCUPIED MODE HEATING SETPOINT.

E. IF THE ZONE TEMPERATURE RISES ABOVE THE UNOCCUPIED MODE COOLING SETPOINT, FOLLOW THE MORNING COOL DOWN MODE SEQUENCE UNTIL ZONE TEMPERATURE IS 2 DEGREES FAHRENHEIT BELOW UNOCCUPIED MODE COOLING SETPOINT.

4. MORNING WARM UP/ COOL DOWN MODE

A. AN OPTIMAL START PROGRAM IS PROVIDED THAT USE THE OUTSIDE AIR TEMPERATURE AND ZONE TEMPERATURE TO DETERMINE START TIME SO THAT THE OCCUPIED ZONE TEMPERATURE SETPOINT IS ACHIEVED 15 MINUTES PRIOR TO OCCUPANCY.

B. THE SUPPLY FAN RUNS CONTINUOUSLY.

C. THE COMPRESSOR IS ENABLED IN HEATING OR COOLING MODE AS NEEDED TO MEET OCCUPIED ZONE TEMPERATURE SETPOINT. D. THE ASSOCIATED DOAS UNIT REMAIN DISABLED ACCORDING TO ITS OWN OPERATING SCHEDULE.

5. ALARMS

A. "LOW ZONE TEMPERATURE ALARM": GENERATE AN ALARM WHEN THE ZONE TEMPERATURE IS 5 DEGREES FAHRENHEIT BELOW SETPOINT FOR 15 MINUTES.

B. "HIGH ZONE TEMPERATURE ALARM": GENERATE AN ALARM WHEN THE ZONE TEMPERATURE IS 5 DEGREES FAHRENHEIT ABOVE SETPOINT FOR 15 MINUTES.

C. "SUPPLY FAN FAILURE": GENERATE AN ALARM WHEN THE SUPPLY FAN IS COMMANDED ON, BUT STATUS IS NOT PROVEN AFTER 30 SECONDS (CALL TO RUN FAIL).

D. "COMPRESSOR FAILURE": GENERATE AN ALARM WHEN THE COMPRESSOR IS COMMANDED ON, BUT THE STATUS IS NOT PROVEN AFTER 30 SECONDS (CALL TO RUN FAIL).

E. "CHANGE FILTER": GENERATE AN ALARM WHEN THE DIRTY FILTER SWITCH IS TRIPPED.
