Indicates a potential hazardous situation which, if not avoided, MAY result in minor or moderate injury. It may also be used to alert against unsafe practices.
Product description Argo Hydro-Air Zoning Controls provide the easiest way to interface between the thermostat and air handler. These dependable control relays will control from 1 to 20 zones of heating/cooling and provide priority switching for domestic hot water. Boiler and A/C condenser wiring is virtually fool proof.

For your convenience it is recommended that the control be mounted as close as possible to the device being controlled, however it should never be mounted more than 75 feet away. Select a location that is easily accessible for installation and service.
Electrical specifications & Wiring ! WARNING ! Electrical shock hazard! Disconnect power before installing or servicing. Can cause severe personal injury, death, or substantial property damage if ignored. General Wiring Notice All primary wiring must be 14 AWG minimum. Torque terminal screws 6 to 7 inch pounds. U.S.A. - National Electric Code and any other national, state, or local code requirements. Wiring must be N.E.C. Class 1. CANADA - C.S.A. C22.
Sequence Of Operation When the thermostat calls for heat, the boiler end switch closes, starting the burner and energizing the heating circulator. The fan will operate at low speed (G1) when the water temperature is above the aquastat setting at the Hydro-Coil. When priority zone is actuated, the priority circulator and boiler end switch is energized. The heating circulator is shut off and the fan will operate at low speed (G1) until the water temperature drops below the aquastat setting.
Terminal Descriptions Continued Aquastat TT- Connect to factory supplied strap-on aquastat at Hydro-Coil. These terminals must be closed for fan the to operate in Heating Mode. Install a jumper if no aquastat is used. Freeze TT- Optional freeze protection when (TT) is connected to aquastat at Hydro-Coil. When closed, these terminals start the heating circulator, but the not fan. Using an SPST aquastat that closes when temperature falls to 40°F with a 5°F differential (MHL 480B), is recommended.
