Honeywell L7148F1075 Oil Aquastat Controller

This component is OBSOLETE AND ONLY AVAILABLE THROUGH OEM. Contact the manufacturer of the equipment this controller is installed within for assistance. Replaces the function of the bulb and capillary electromechanical Aquastat® Controller with electronic temperature sensing and microprocessor controlled relays. Combination Aquastat® and high limit controller is intended for use in gas-fired boilers using a 24 Vac burner circuit with vestibules for a wiring enclosure. Can replace a Honeywell L4080 High Limit and R8285 Transformer Relay. Used in gas boilers where ignition controls such as the Honeywell S8600 Spark Ignition or SV9500/SV9501 SmartValve™ controls or standing pilot gas controls such as the Honeywell VR8300 are powered from 24 Vac. An external 120 Vac to 24 Vac transformer with 10 VA minimum is required to power the L7148F. For total external transformer VA requirements, add the 10 VA requirements for the control, gas valve load requirement (connections B1, B2), zone valve connection requirement (see zone valve specifications), vent damper requirement and VA requirement for any other equipment. Total low voltage load must not exceed 4A. Available with quick-connect or AMP© plug connections. W, R and C terminals are provided in a terminal block with screw connections.
