Output terminals. P. 9 Transformer: A single 24 Volt AC Transformer (40 or 100 VA) is included to power all Arzel equipment, Fossil Fuel Back-up Switch: Switches customize the dampers and thermostats. system operation for a Fossil Fuel backup furnace P.
One 24-Volt AC transformer (provided with the system) powers all zone thermostats, and the Arzel Control Panel. The HVAC system transformer provides power for the heating and air-conditioning equipment outputs only. Do not mix HVAC and Arzel transformer outputs. A positive ground terminal is provided for grounding connection. (Fig. 5a) Rev.
EQUIPMENT TYPE SET UP ( FURNACE / HEAT PUMP ) The Arzel AirBoss™ System is factory set for furnace applications. Any time the board PWR switch is turned ON, the system will automatically check itself and flash the appropriate LED to indicate the type of equipment it is set up to handle.
HVAC Output The AirBoss™ controls the HVAC equipment through a set of six “dry contact” output relays. When a thermostat calls for equipment operation, the AirBoss™ closes the appropriate output relays, sending the “R” signal from the HVAC Transformer back to the appropriate equipment terminals.
EMERGENCY HEAT OPERATION (HEAT PUMP ONLY ) All Arzel AirBoss™ system boards have emergency or backup heat capability. When the Emergency heat mode is activated it will convert all “Y” signals to “W” signals, thus bypassing heat pump operation and activating backup heat.
When switched to “Fossil Fuel” and the system is operated in emergency heat mode, the Arzel board will add 50° F to the “HTG. LAT” set-point (up to a safety maximum of 190° F). *NOTE* Arzel controls must be used as secondary controls only.
If you do not wish to use either or both, place the unused rotary switch pointer to the Off position. You must install the sensor or place both rotary switches to the Off position. Self Test: The Arzel Panel automatically detects an open or shorted LAT sensor and locks out the equipment accordingly.
SMART SLAVE ZONE (SSZ™) Thermostat Any number of Smart Slave Zones may be added to all Arzel panels. The Smart Slave Zone thermostat does not control the HVAC equipment. It will only open its zone dampers if the air temperature in the duct is compatible with the thermostat call.
This switch will start the pumps manually and with the “Power” switch in the OFF position, all the zone dampers will open. This will aid in troubleshooting by allowing the operation of the HVAC system independent of the Arzel panel, if you suspect a PC board failure.
IDENTIFYING THE ZONES Tubing is available in eight colors for easy tracing and identification of dampers. To avoid zone mix-ups, mark all supply ducts clearly with room designation and proper zone number. The Arzel Duct-Finder™ makes duct tracing easy. DAMPER POSITION INDICATOR Observe the movements of the damper position indicator (Fig.
1. Connect the pressure switch NORM OPEN and COMMON terminals (Fig. 16a) to terminals A and B on the Arzel board (Fig. 16b) with standard 18-2 wire. The pressure switch must be mounted in a vertical position with the pressure tap at the bottom.
1. Set all thermostats to the “Off” position and all fan switches to the “Auto” position before starting the checkout procedure. 2. Turn power ON to the Arzel panel and the HVAC equipment, the green LED next to the “Power” switch will come on.
