ZONING CHECKLIST
SMARTZONE & THERMOSTATS
q
CALCULATE MINIMUM 24VAC TRANSFORMER VA CAPACITY
q
CHECK PRIMARY AND SECONDARY VOLTAGE FOR ZONING TRANSFORMER.
MAKE SURE SEPARATE TRANSFORMER AND CIRCUIT IS USE FROM
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).
STATS WITH GAS/ELECTRIC EQUIPMENT.
DUCT & DAMPERS
q
DESIGN ALL ZONES TO BALANCE THE CFM EVENLY (EACH ZONE SHOULD BE
SIMILAR IN SIZE).
q
AVOID CREATING SMALL ZONES (< 20% OF TOTAL CAPACITY).
q
USE PROPER EXCESS (SURPLUS) AIR-FLOW MANAGEMENT INCLUDING
THESE TECHNIQUES –BYPASS DUCT/DAMPER, DUMP ZONE(S) OR ADJUST
DAMPERS MAX CLOSE SETTINGS 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
q
REFER TO DUCT DESIGN & BYPASS
HVAC EQUIPMENT
q
PERFORM BASIC EQUIPMENT CHECK INCLUDING COMPRESSOR,
REFRIGERANT CHARGE, BLOWER, FURNACE, FILTER BEFORE INSTALLING
OR STARTING UP SMARTZONE SYSTEM.
