ZONING CHECKLIST
q
DESIGN ALL ZONES TO BE SIMILAR IN CFM CAPACITY AS MUCH AS
POSSIBLE (BALANCED ZONES = LESS PRESSURE RELIEF NEEDED)
q
AVOID CREATING SMALL ZONES (< 20% OF TOTAL CAPACITY)
q
PROVIDE SUPPLY AIR DUCT PRESSURE RELIEF (SURPLUS AIR-FLOW
MANAGEMENT) USING THESE TECHNIQUES –BYPASS DUCT/DAMPER,
DUMP ZONE(S) OR SET MAX CLOSE ON DAMPER TO ALLOW LEAKAGE
q
ECOJAY RECOMMENDS THE USE OF A BYPASS DUCT/DAMPER THAT IS
LARGE ENOUGH TO ACCOMMODATE THE TOTAL SYSTEM CFM CAPACITY
MINUS THE CFM CAPACITY OF THE SMALLEST ZONE AND THE CFM
PROVIDED BY ANY ADDITIONAL PRESSURE RELIEF
q
REFER TO DUCT DESIGN & BYPASS (PAGE 3 & 4)
q
CALCULATE MINIMUM 24VAC TRANSFORMER VA CAPACITY (PAGE 5)
q
CHECK PRIMARY AND SECONDARY VOLTAGE FOR ZONING TRANSFORMER
*MAKE SURE SEPARATE TRANSFORMER AND CIRCUIT IS USED (DO NOT
USE EQUIPMENT TRANSFORMER)
q
SELECT MOUNTING LOCATION THAT PROVIDES SPACE AND EASY PATH TO
RUN WIRES
q
MOUNT THERMOSTATS WHERE NOT EXPOSED DIRECTLY TO AIR STREAM
FROM SUPPLY AIR GRILLS, RADIANT HEAT FROM WINDOWS OR
SKYLIGHTS, OR TOO CLOSE TO RETURN AIR
q
USE THERMOSTATS THAT ARE NOT ‘POWER STEALING’ OR TRIAC BASED
q
GAS/ELECTRIC OR HEAT PUMP STATS CAN BE USED ON HEAT PUMP
EQUIPMENT (HEAT PUMP STAT IS REQUIRED ON ZONE 1 ONLY IF
EMERGENCY HEAT CONTROL IS NEEDED)
NOTE: USE ONLY GAS/ELECTRIC
STATS WITH GAS/ELECTRIC EQUIPMENT
DUCT & DAMPERS
SMARTZONE & THERMOSTATS
q
PERFORM BASIC EQUIPMENT CHECK INCLUDING COMPRESSOR,
REFRIGERANT CHARGE, BLOWER, FURNACE, FILTER BEFORE INSTALLING
OR STARTING UP SMARTZONE SYSTEM.
