A. Run Conditions - Continuous:
1. The unit shall be interlocked with ECRT-EF-501 and ECRT-EF-502 and shall not
operate if both exhaust fans are inoperable, and shall maintain:
a. A 80°F (adj.) cooling setpoint
b. A 65°F (adj.) heating setpoint.
B. Control - Building Supply Air Flow:
1. The supply fan shall run when commanded on.
2. The controller shall measure building sludge loading bay supply air flow and modulate
the supply fan VFD speed to maintain an offset air flow between the Exhaust Air Flow
and the Supply Air Flow, offset setpoint of 1,135 cfm (adj.) (4,100 cfm exhaust flow –
2,965 cfm Sludge Loading bay supply flow). The supply fan VFD speed shall not drop
below 20% (adj.).
C. Alarms shall be provided as follows:
1. High Building supply air flow: If the building supply air flow is 25% (adj.) greater than
setpoint.
2. Low Building supply air flow: If the building supply air flow is 25% (adj.) less than
setpoint.
3. High Zone Temp: If the zone temperature is greater than the cooling setpoint by a user
definable amount (adj.).
4. Low Zone Temp: If the zone temperature is less than the heating setpoint by a user
definable amount (adj.).
