1 Excellence ithout ompromise NTLS IN. T E H N I A L U L L E T I N s ESTE & EST3E ongratulations on purchasing the STE/ST3E series ULTAZNE ontrol Panel. The ST series of zone control panels are still the same popular, field proven zone control panels that have been in use for the last seventeen years! The new E series revision has a few upgrades to enhance the reliability, prote cti on and operati on of th e board. First and most important is the replacement of the old 3 amp sloblo fuse, with an integrated Thermal ircuit breaker or Polyfuse. This means no more running to the electronics store to buy a fuse, after the spare fuse that was provided has blown. The Polyfuse protects the panel against shorts in the thermostat or damper field wiring. It does not protect against shorts in the H V A equi pm ent f i el d w i r i ng. S ee page.

The J jumper enables fan operation in Heat mode as well as ooling mode. ith the exception of the Polyfuse and the J jumper, all other changes have no direct bearing on the wiring, i n s t a l l a t i o n, o r o p e r a t i o n o f t h e c o n t r o l p a n e l. The ST series zone control panels are the most versatile and rugged relay based logic control systems in use today. The Master/Slave circuitry of these panels can be utilized to satisfy numerous control applications and job specifications. PAE TALE F NTENTS Introduction & Specifications Application Notes Typical 5 zone control panel diagram Thermostat equirements heckout Procedures EST3E iring Diagram The heating/cooling changeover operation is still controlled by a changeover subbase on the zone thermostat, or a separate remote selector switch can be used instead. This allows for inexpensive standard or 3 wire thermostats to be used in all z o n e s d e p e n d i n g o n t h e f i e l d a p p l i c a t i o n. The table on Page shows the types of digital programmable thermostats that are compatible with the STE or ST3E panels. The diagrams included with this bulletin are based upon the most frequently asked questions regarding the wiring of these panels. There are additional diagrams available through the Te ch n i ca l S u p p o r t H o t l i n ontact the Hotline if you find yourself on the job site and unsure of the exact wiring for your ST Series ontrol Panel.

2 PEATIN IIN. HEAT MDE: To operate the system in the heat mode, the "" terminal has to be made to the "" terminal on the zone terminal block. This allows any zone thermostat to call for heat. hen a zone calls for heat, the control panel closes the circuit from "" to "" activating the furnace. The zone damper calling for heat remains open and zones satisfied will close. The fan and limit control in the furnace will operate the fan.. L MDE: To operate the system in the cool mode, the "" terminal has to be made to the "" terminal on the zone terminal block. This allows for any thermostat to call for cooling. n call for cooling, terminals "", "" and "" are made to bring on the fan and compressor. The dampers for zones calling will remain open; the dampers satisfied will close. 3. FF PSITIN: hen the subbase on zone is in the "FF" position the entire system is disabled.. NTINUUS FAN: hen placing the fan switch on the subbase from "AUT" to "N" position, the panel closes the circuit between "" and "" terminals to energize the fan relay. 5. LSE SITHES: If left in the open position when all zones satisfy, the damper will drive to open position. If left in closed position, when all zones satisfy, the damper will remain closed unless it is the last zone to satisfy; then it will remain open. NTE: The last zone to satisfy will always be open regardless of position of switch. AP PL IA TI N #: IIN DIAAM HEATIN NL INSTALLATIN. HVA SSTEM: iring the HVA system to the ESTE or EST3E is typical of wiring a subbase to a heating/cooling system. ( wires required.) The following terminals are on the system terminal block: ire to the H heating transformer and/or the cooling transformer. ire to the ompressor elay. ire to Heat ontrol (gas valve, oil burner relay) on system terminal block. ire to Fan elay.. TANSFME V VA: A separate V VA transformer is required to be wired to terminals and of the terminal block labeled "TFormer". ( wires required.) This transformer powers the panel board, thermostats and damper motors. It does not power the furnace or the air conditioner. The board is now protected by a Thermal Polyfuse at the transformer input. hen the polyfuse trips it will get quite hot. To reset the breaker, remove the VA for approximately 3 seconds. heck the damper motors and field wiring for shorts. If adding two panels together, be sure of wiring in ( and ) circuit. 3. ZNE DAMPE MTS: Use 3 conductor wire from each set of MAN or DN zone damper terminals or conductor wire on "S" dampers to the panel. See diagrams # and 5 when wiring more than one damper per zone. N TES. THEMSTATS: ZNE : Thermostats that have subbases with "" and "" terminals are required to enable system changeover. These include mechanical and battery operated thermostats ( wires required terminals,,,, and ), and electromechanical and programmable digital thermostats ( VA, 7 wires required terminals,,,,, and ). If model MSD remote selector switch is used, it will be wired to the zone terminal block in place of the changeover subbase (7 wires required total: on the MSD,, and ; 3 on the thermostat, and ). See diagram #3. THE ZNES: 3 wires are required for mechanical and battery operated thermostats terminals, and. wires are required for electromechanical and VA digital thermostats terminals,, and. No subbases required. See page for specific types of thermostats required. 5. HEAT NL L NL APPLIATINS: Zone no longer requires a subbase or remote switch. All zones need only a two or three wire thermostat to operate in either heat or cool. #: IIN DIAAM LIN NL INSTALLATIN rol D D D Panel K ZNE ZNE THEMSTAT rol D D D Panel K ZNE ZNE THEMSTAT D D ZNE ZNE THEMSTAT D D ZNE ZNE THEMSTAT D D D AUTIN FIELD INSTALLED JUMPE 7 D D D AUTIN FIELD INSTALLED JUMPE D D D ADDITINAL ZNE PANEL D ADDITINAL ZNE PANEL NTL SSTEM NTL SSTEM E ontrols Inc. 385 Highway 33, NJ FA 7353
