Honeywell L8148A1017/U Aqua Stat Relay 140-240 F (Immersion)

Product Description

The Honeywell L8148A1017/U is an immersion-type aquastat relay for hydronic heating systems that provides high-limit protection and relay control of burner and circulator motors. It is factory-set for a 140 to 240 F temperature range with an 8 F fixed differential and is compatible with 120 VAC supply while providing a low-voltage control circuit for a 24 VAC thermostat. Mounting can be horizontal or vertical and models include well adapter and range stops.

• High-limit protection with 140 to 240 F operating range and 8 F fixed differential; high limit opens burner circuit only.
• Immersion relay with relay control for burner and circulator motors; compatible with 120 VAC input and low-voltage 24 VAC control circuit.
• Mountable horizontal or vertical; sensing element (immersion well) options and TRADELINE models include well adapter, heat-conductive compound, and range stops.

Product Highlights

Immersion aquastat relay, 140�240 F range, 8 F fixed differential, 120 VAC input with 24 VAC control circuit, horizontal or vertical mounting.
