What is HZ311?
The TrueZONE® HZ311 Panel is for conventional, single stage applications for up to 3 zones (1H, 1C) at 24 Volts. It features robust push terminals, common-sense LEDs, variable-speed fan control, and leaves a smaller environmental footprint.
What is a zone panel?
A zoning system is a professionally installed control system consisting of a damper and thermostat for each room or zone of the house. This control system is wired into a central control panel that sequences each thermostat’s call with the zone dampers in the ducts and the HVAC system.
How do you purge a Honeywell hz311?
What is Honeywell Purge Control? When the zone panel cover is removed, the EMERGENCY HEATING / EXCLUSION PURGE button is visible. Press this button during panel cleaning (at startup or after a heating / cooling request) to stop cleaning and save time during installation or troubleshooting.
What does a dats sensor do?
The C7835A1009 Discharge Air Temperature Sensor (DATS) is a duct-mounted temperature probe that provides capacity control of heating and cooling equipment. The DATS also compares the discharge air temperature to the room temperature and, if out of tolerance, a heating or cooling alert is issued.
Can two thermostats control one zone?
Thermostats in zoned systems can control the same heating and cooling system or each thermostat can control its own system. When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house.
What does purge override mean?
When the zone panel cover is off, the EMERGENCY HEAT/PURGE OVERRIDE button is visible. When the panel is in Purge (at startup or after a call for heat/cool), pressing this but- ton stops the Purge, which saves time during installation or troubleshooting.
What is zoning in HVAC?
An HVAC zoning system (also referred to as “zoned HVAC”) is a heating and cooling system that uses dampers in the ductwork to regulate and redirect air to specific areas of the home. This allows for the creation of customized temperature zones throughout the home for increased comfort and efficiency.
What are the three zone controls?
A zone control system consists of 3 basic components: thermostats, a control panel, and electronic dampers.
What does purge mean on a Honeywell hz311?
“Purging” is the process of clearing an air conditioner’s (AC’s) unit’s internal lines and hoses. This is frequently done before recharging freon but. many newer model AC units, such as Honeywell units, purge the system on startup.
Where do I put Honeywell dats?
The location of the DATS is critical; it should not be placed in line-of-sight of the heat exchanger or cooling coil because the DATS could activate prematurely. It should also be located before the bypass damper, when applicable.
