Honeywell L8124A1007 Triple Aquastat Relay

Features

• Immersion-type controllers that combine high limit protection with low limit and circulator control in forced hydronic heating systems.
• Provide multizone control by using a separate circulator and R845 Relay for each zone.
• Include diaphragm powerhead and Micro Switch™ assembly that respond to temperature changes in boiler water.
• Mount directly to boiler.
• Select models include large transformers and extra terminals for supplying power to low voltage zone valves.
• Require 24 Vac thermostat with heat anticipator set at 0.2 A (plus current draw of gas valve on L8124E).
• TRADELINE models include tube of heat conductive compound and range stops.
