ZONING CHECKLIST
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
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). NOTE: USE ONLY GAS/ELECTRIC
STATS WITH GAS/ELECTRIC EQUIPMENT.
DUCT & DAMPERS
SMARTZONE & THERMOSTATS
q PERFORM BASIC EQUIPMENT CHECK INCLUDING COMPRESSOR,

AIR NOISE
SHOULD BE ALWAYS BE MINIMIZED AND IN A ZONING SYSTEM WITH OPENING &
CLOSING DAMPERS IT CAN BE MORE CHALLENGING. INSTALL THE DAMPER AS
CLOSE AS POSSIBLE TO THE SUPPLY PLENUM TO PREVENT AIR NOISE
TRANSMISSION INTO THE CONDITIONED SPACE. TO MINIMIZE NOISE AND
MAINTAIN ADEQUATE THROW, SUPPLY AIR DUCT SYSTEM SHOULD BE DESIGNED
TO PROVIDE 600 TO 700 FPM VELOCITY AIRFLOW. THIS CAN BE ACHIEVED BY
PROVIDING LARGE ENOUGH DUCTS/DAMPERS TO SUPPLY THE VOLUME (CFM)
OF AIR NEEDED FOR THE ZONE. USE THE “NORMAL CFM” CHART TO CHECK
ROUND DUCT SIZE(S) THAT WILL ACHIEVE THIS VELOCITY.
►FOR ZONES WITH MULTIPLE DAMPERS, THE TOTAL ZONE CFM IS THE SUM OF
ALL THE DAMPERS “NORMAL CFM”
►FOR RECTANGULAR DUCT SYSTEMS USE THE RECTANGULAR CFM EQUATION
PROVIDED FOR “NORMAL CFM”
ZONE BALANCING
TO MAINTAIN OPTIMAL EQUIPMENT PERFORMANCE IN A TYPICAL ZONING APPLICATION, IT IS PREFERABLE TO DESIGN ALL ZONES TO BE
CLOSE TO EQUAL IN SIZE.(IN TERMS OF CFM). THIS DOES NOT MEAN THAT EVERY ZONE MUST HAVE EXACTLY THE SAME CFM REQUIREMENTS
BUT THE SYSTEM WILL WORK MOST EFFICIENTLY IF THEY ARE APPROXIMATELY THE SAME SIZE. FOLLOWING THIS GUIDELINE WILL MINIMIZE
THE AMOUNT OF PRESSURE RELIEF (BYPASS) NECESSARY. FOR MOST RESIDENTIAL ZONING INSTALLATIONS USING SINGLE SPEED
EQUIPMENT, AVOID CREATING MORE THAN THREE ZONES WITH NO ZONE SMALLER THAN 20% OF THE TOTAL EQUIPMENT CFM CAPACITY.
SMARTZONE DUCT SYSTEM
A ZONING SYSTEM CAN TYPICALLY USE THE SAME DUCT SIZING AS A TRADITIONAL SINGLE-THERMOSTAT SYSTEM IF THE PRESSURE RELIEF
IS INSTALLED CORRECTLY AND THE SYSTEM IS 4 OR LESS ZONES. TO MINIMIZE BYPASS AIR FLOW, INCREASE THE DUCT CAPACITY BY ONE
SIZE FOR EACH ZONE LESS THAN 25% OF THE TOTAL SYSTEM AIR FLOW CAPACITY AS SYSTEMS GET LARGER THAN 4 ZONES, IT MAY
BECOME NECESSARY TO INCREASE THE DUCT & DAMPER SIZES OF THE SMALLER ZONES (OR ALL THE ZONES) IN ORDER TO MINIMIZE THE
AMOUNT OF PRESSURE RELIEF NEEDED WHEN ONLY THE SMALLEST ZONE IS OPEN.
NOTE: CONNECT DAMPERS DIRECTLY TO THE PLENUM WHEN POSSIBLE AND BRANCH OFF SMALLER DUCTS GOING TO DIFFERENT AREAS
WITHIN THE ZONES. USING THIS TRUNK/BRANCH DUCT DESIGN WILL MINIMIZE COST AND REDUCE AIR NOISE.
DESIGN & PRE-INSTALL
RETURN AIR
PROBLEMS WITH ZONING CAN
OCCUR WHEN THE RETURN AIR
REGISTERS OR DUCT ARE
UNDERSIZED. INSUFFICIENT CFM
WILL PREVENT SATISFYING VELOCITY
REQUIREMENTS WHEN ALL DAMPERS
ARE OPEN. TO ENSURE THE RETURN
AIR IS LARGE ENOUGH, VERIFY THAT
ITS SURFACE AREA IS SUFFICIENT TO
PASS FULL SPEED BLOWER CFM.
ENSURE ALL ZONES HAVE
UNRESTRICTED AIRFLOW PATH
“BACK” TO A RETURN AIR GRILL
EQUIVALENT TO THE ZONE CFM.
ROUND AND RECTANGULAR DAMPERS
SPRING DAMPERS USE A MOTOR TO POWER THE DAMPER BLADE IN ONE
DIRECTION AND A SPRING TO MOVE THE BLADE IN THE OPPOSITE DIRECTION.
WHEN POWER IS APPLIED TO THE DAMPER, THE MOTOR MOVES THE BLADE.
WHEN POWER IS REMOVED, THE SPRING MOVES THE BLADE IN THE OPPOSITE
DIRECTION.
WARNING: SPRING DAMPERS CONSUME MORE ELECTRICITY THAN POWER-OPEN/
POWER-CLOSE DAMPERS. (10 TO 12 VA WHEN POWERED)
POWER DAMPERS POWER OPEN /POWER CLOSE DAMPERS USE THREE WIRES
TO POWER THE DAMPER OPEN OR POWER IT CLOSED. THE ZONE PANEL IS
RESPONSIBLE FOR SUPPLYING A 24VAC SIGNAL TO EITHER THE PO (POWER
OPEN) OR PC (POWER CLOSED) TERMINAL OF THESE DAMPERS. PRIMARY
ADVANTAGES OF POWER OPEN/POWER CLOSE DAMPERS INCLUDE LOWER
POWER CONSUMPTION, QUIET
OPERATION AND GREATER RELIABILITY. (2.5 TO 3VA)

MODES & STAGING
TIME DELAY
TIME DELAY IS DESIGNED FOR EQUIPMENT PROTECTION. AFTER CALLS FROM ALL ZONES HAVE BEEN SATISFIED AND THE EQUIPMENT IS DE-
ENERGIZED, A 3-MINUTE TIME DELAY WILL BE COMPLETED BEFORE NEW THERMOSTAT CALLS WILL BE PROCESSED. DURING THE DELAY ALL
DAMPERS OPEN AND THE EQUIPMENT WILL NOT RUN. DURING DELAY THE DIGITAL DISPLAY WILL COUNT DOWN THE NUMBER OF SECONDS
LEFT DURING PURGE TIME IF A NEW CALL IS ENERGIZED. NOTE: ALTHOUGH SMARTZONE WILL NOT ENERGIZE THE FAN (OR EQUIPMENT)
DURING DELAY, THE EQUIPMENT BEING USED MAY HAVE A BUILT IN CONTROL THAT CAUSES THE FAN TO CONTINUE RUNNING.
A 3 MINUTE PURGE OF THE SUPPLY AIR PLENUM IS INITIATED DURING OPPOSING-CALL CHANGEOVER. (SWITCHING FROM HEAT TO COOL
OR COOL TO HEAT) DURING THE PURGE, THE FAN WILL REMAIN ENERGIZED TO PURGE EXISTING SUPPLY AIR TEMPERATURE AND TO
ALLOW EQUALIZATION OF HVAC SYSTEM PRESSURES BEFORE ENERGIZING THE OPPOSING MODE CALL. DURING THE PURGE MODE,
ZONE(S) CALLING FOR THE OPPOSITE MODE WILL HAVE DAMPER(S) CLOSED. ALL OTHER DAMPERS (NON-CALLING ZONE(S) AND ZONE(S)
CALLING FOR MODE LAST ENERGIZED) WILL REMAIN OPEN DURING PURGE MODE. DURING PURGE THE DIGITAL DISPLAY WILL COUNT
DOWN THE NUMBER OF SECONDS LEFT DURING PURGE TIME (SEE “AUTO CHANGEOVER”)
AUTO CHANGEOVER
IT IS POSSIBLE TO HAVE A ZONE(S) CALLING FOR COOL AND ANOTHER ZONE(S) CALLING FOR HEAT (CALLED “OPPOSING CALLS”). WHEN
OPPOSING CALLS EXIST, EACH ACTIVE MODE RUNNING ON THE EQUIPMENT WILL BE LIMITED TO A MAXIMUM RUN TIME OF 15 MINUTES
STARTING WHEN THE OPPOSING MODE CALL IS RECEIVED. IF THE ACTIVE MODE DOES NOT SATISFY THE CALLING ZONE(S) IN THIS 15
MINUTE INTERVAL, SMARTZONE WILL INITIATE A CHANGEOVER PROCESS. CHANGEOVER: DE-ENERGIZE THE ACTIVE MODE AND INITIATING
A 3 MINUTE PURGE (SEE PAGE 3 FOR MORE ABOUT PURGE). DURING PURGE, ALL DAMPERS OPEN DURING THE PREVIOUSLY ACTIVE MODE
REMAIN OPEN AND THE FAN REMAINS ENERGIZED TO NEUTRALIZE THE SUPPLY AIR TEMPERATURE BEFORE ENERGIZING THE OPPOSING
CALL MODE ON THE EQUIPMENT CHANGEOVER PROCESS.
►EMERGENCY HEAT CAN ONLY BE OPERATED BY A HEAT PUMP THERMOSTAT CONNECTED TO THE ZONE 1 “W” THERMOSTAT TERMINAL.
►IF ZONE 1 THERMOSTAT CALLS FOR EMER. HEAT, THE SMARTZONE SYSTEM WILL BE LOCKED INTO EMERGENCY HEAT.
►THE COMPRESSOR WILL NOT ENERGIZE AND ONLY HEATING CALLS WILL BE RECOGNIZED FROM ANY ZONE OTHER THAN ZONE ONE.
ONLY W1/EH AND G WILL BE ALLOWED TO ENERGIZE WHILE SMARTZONE IS LOCKED INTO EMERGENCY HEAT. (IE. COMPRESSOR &
COOLING CALLS WILL BE LOCKED OUT) ALL COOLING CALLS FROM ZONES 2 THRU 20 WILL BE IGNORED AND ANY HEATING CALL FROM
THESE ZONES WILL BE TREATED BY THE SMARTZONE SYSTEM AS EMER. HEAT.
►TO UNLOCK AND TAKE THE SYSTEM OUT OF EMER. HEAT, REMOVE THE EMER. HEAT CALL AT THE ZONE 1 THERMOSTAT AND MAKE A
CALL FOR COMPRESSOR HEAT OR COOLING FROM THIS THERMOSTAT.
EMERGENCY HEAT
DUAL FUEL (FOSSIL FUEL AUX / EM HEAT)
IN DUAL FUEL MODE, THE COMPRESSOR(S) WILL NOT RUN WHEN AUXILIARY HEAT IS ENERGIZED. SMARTZONE CONTROLS DUAL FUEL SO A
“DUAL FUEL KIT” AND HEAT PUMP THERMOSTATS ARE NOT REQUIRED. GAS/ELECTRIC THERMOSTATS MAY BE USED WITH A HEAT PUMP
SYSTEM, HOWEVER, USE A HEAT PUMP STAT FOR THE ZONE 1 THERMOSTAT TO CONTROL EMERGENCY HEAT (DESCRIBED ABOVE). ALWAYS
INSTALL THE HEAT PUMP EVAPORATOR DOWNSTREAM OF THE FURNACE, THIS PREVENTS CONDENSATION IN THE HEAT EXCHANGER DURING
THE COOLING MODE. SEE EQUIPMENT STAGING FOR MORE DETAILS ABOUT DUAL FUEL.
PURGE
1
THE SMARTZONE CONTROLS EQUIPMENT STAGING AUTOMATICALLY BASED ON TIME AND SUPPLY AIR TEMPERATURE. (THIS TEMPERATURE IS
READ BY THE INCLUDED SUPPLY AIR TEMP SENSOR –SAS) NOTE: WITHOUT THIS SENSOR INSTALLED, THE SMARTZONE WILL NOT RUN 2ND
STAGE OR OPERATE ANY DAMPERS. TIME AND TEMPERATURE SETTINGS VARY ACCORDING TO THE TYPE OF EQUIPMENT HI/LO TEMP LIMIT
SETTINGS. STAGING WILL OCCUR ONLY WHEN THE MINIMUM RUN-TIME AND TEMPERATURE RANGE CONDITIONS ARE MET. THE FACTORY
DEFAULT SETTINGS FOR TEMPERATURE CUT-IN AND CUT-OUT ARE ADJUSTABLE. (SEE “HI & LO LIMIT ADJUST”)
NOTE: G WILL ENERGIZE IMMEDIATELY WITH 1ST STAGE IF DIP SWITCH #5 IS SET TO
“ELECTRIC”. IF SET TO THE DEFAULT OF “GAS”, G WILL ENERGIZE AFTER 90 SECONDS.
