Page 3: Overview
OVERVIEW The ZP4-ESP-FAV is a residential and light commercial forced air zone control system that allows a single HVAC unit to have up to 4 separate zones. The panel can be used with single stage or multi- stage heat/cool equipment as well as heat pump and dual fuel systems having up to 3 stages of heating and 2 stages of cooling. -

Page 5: System Wiring
Use appropriate anchors and screws to secure the panel to the surface. System Power 1. Wire a 24VAC, 75VA transformer to the 24VAC ‘R’ and ‘C’ terminals on the ZP4-ESP-FAV panel. 24VAC 120/208/240/480 VAC... -
Page 6: Dh Terminals
SYSTEM WIRING DH Terminals The ZP4-ESP-FAV has a set of terminals marked DH that are a normally open dry contact input designed for an optional dehumidistat. When the HVAC system is in the cooling mode and the humidity is above the dedhumidistat setpoint, the cooling setpoint will be overridden and the equipment will continue to run until either the dehumidistat setpoint is reached or the equipment is shut off... -
Page 7: Sensors
SYSTEM WIRING SENSORS The SENSOR terminals provide inputs for Discharge Air (DAS), Return Air (RAS) and Outdoor Temperature (OTS) sensors. All sensors are NTC Type III thermistors rated at 10K Ohms @ 77° F. Discharge Air Sensor Mount the discharge air sensor in the main supply duct out of the line of sight of the heat exchanger or cooling coil and upstream of any duct transitions or zone dampers. -
Page 8: Sps Terminals
SYSTEM WIRING SPS Terminals The SPS terminals wire to the ZPA-SPS Static Pressure Sensor. The sensor should be installed on a flat surface so that the diaphragm is in the vertical position. Use the 1/4” x 36” tubing provided and connect one end to the (P1+) high pressure fitting on the sensor. -
Page 9: Using A Conventional Electronic Bypass Damper
3 Open CO2 Sensor The ZP4-ESP-FAV panel has an input for a CO2 sensor having a normally open dry contact output. When CO2 reaches a pre-selected setting on the sensor, the CO2 contacts will close causing a fresh air damper to open and the system fan to run regardless of what mode the equipment is in. Once the CO2 level falls below the sensor setting, the contact will open and the fresh air damper will close and the fan will go intermittent with the equipment. -
Page 10: Fad Fresh Air Damper
SYSTEM WIRING FAD (Fresh Air Damper) The ZP4-ESP-FAV has a fresh air damper terminal designed to be used with a 24VAC Power Open / Spring Close, 2-wire damper. The fresh air damper can be used for both timed fresh air ventilation and/or CO2 ventilation. -
Page 11: Panel Setup
PANEL SETUP Switch Configurations The ZP4-ESP-FAV panel has a row of slide switches that are used to configure the panel for the specific equipment application. The switches also provide other control options. System Configuration Switch 1 selects the type of system. Heat Pump or Heat / Cool Switch 2 selects the type of Heat Pump. -
Page 12: Gdm (Graphic Display Module)
The GDM is backlit and has been factory calibrated to provide the best contrast. Discharge Air Sensors When the ZP4-ESP-FAV panel is first powered up, the GDM will illuminate and Discharge momentarily display the firmware version information and then the Discharge No Sensor Air Temperature. -
Page 13: Setting High Balance Point
PANEL SETUP Setting High Balance Point High Balance Point only functions in heat pump and dual fuel configuration. It is designed to prevent the auxiliary heat from coming on if the outdoor air High BP temperature is above the High Balance Point setpoint. Press the SELECT 60 °F button to display the High BP. -
Page 14: Ventilation Timer
PANEL SETUP Ventilation Timer The Ventilation Timer is designed to improve residential indoor air quality. This is accomplished by introducing fresh, outside air through a fresh air damper controlled by a logic panel. The panel controls the amount of fresh air required each hour based on the ASHRAE 62.2 - 2013 Ventilation and Indoor Air Quality Vent Timer Standard. -
Page 15: Ventilation Timer Hi Limit
PANEL SETUP Ventilation Timer Hi Limit When an outdoor sensor is wired to the panel and Timed Ventilation is being used, the fresh air damper will remain closed if the temperature exceeds the Hi Vent Hi Limit Limit setting which is adjustable from 60° F to 90° F in 1 degree increments. The factory default is Disable. -

‘G’ fan relay to open or close the Clock Contact ‘NS’ terminal on the ZP4-ESP-FAV panel that places the system in the occupied or unoccupied mode of operation. The thermostat can also be used with a T-S1 Indoor Remote Sensor. 24 volt power to the thermostat is supplied by the panel through dedicated Clock Power terminals ‘C’... -
Page 17: How It Works
(Automatic). When in Automatic mode, the fan relay will only energize when the temperature falls below or rises above the programmed unoccupied heating and cooling setpoints. RECOMMENDED SETUP: After mounting and wiring the thermostat subbase to the ZP4-ESP-FAV panel, follow the recommended setup and scheduling steps. SYSTEM SWITCH SETTINGS: The UT32-NS contains a set of four system switches located on the printed circuit board on the back of the thermostat. -
Page 18: Programming Events
OPTIONAL NIGHT STAT SETUP AND SCHEDULING PROGRAMMING EVENTS: When the thermostat is configured to provide 2 schedules per day (Occupied/Unoccupied), 7 days per week, each event is displayed on the LCD as DAY (Occupied) and NIGHT (Unoccupied). 1. Touch and hold Program until Mon (Monday) flashes. 2. - Page 19 www.iohvaccontrols.com For Technical Support Call Toll Free: 866-225-5032 iO-06-1376-101823...
