Overview

Immersion-type controllers that combine high limit protection with low limit and circulator control in forced hydronic heating systems, including domestic hot water service.

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.
