Immersion type controllers that combine high limit protection with low limit and circulator control in forced hydronic heating systems
• Provide multi-zone 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 amp (plus current draw of gas valve on L8124E)
