85 Thermostats AQUASTAT CONTROLLERS L4006A1678 Aquastat Controller High or Low Limit Overview Aquastat Controllers are immersion type devices for limiting or regulating the temperature of liquids in boilers, storage tanks, and other applications where temperature control is required. Features: Totally enclosed Micro Switch snap-acting switches operate on temperature rise to setpoint. Visible control point scale and external adjustment screw permit easy setting. Horizontal or vertical insertion of the sensing element. Direct or well immersion of the sensing element. Models available for strap-on mounting. Remote bulb model may be used to sense air temperature in ducts and in outside air sensing applications. SOURCE 1 PART NO. DESCRIPTION MLP $ S1-L4006A1678 HIGH OR LOW LIMIT AQUASTAT CONTROLLER 250.83 L7224U1002 Aquastat Controller for Oil 120 Vac oil electronic Aquastat Controller with EnviraCOM communication SOURCE 1 PART NO. DESCRIPTION MLP $ S1-L7224U1002 120 VAC OIL ELECTRONIC AQUASTAT CONTROLLER 359.96 L8124 Triple Aquastat Relay 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). SOURCE 1 PART NO. DESCRIPTION MLP $ S1-L8124A1015 TRIPLE AQUASTAT RELAY 556.71 S1-L8124C1003 TRIPLE AQUASTAT RELAY 556.71 S1-L8124E1016 TRIPLE AQUASTAT RELAY 545.48 Honeywell R8182D Protectorelay and Hydronic Heating Controllers Immersion type Aquastat controller and oil burner primary control provides high limit and low limit/circulator control for oil-red hydronic heating systems. Features: Use in intermittent ignition applications. Capable of zone control with zone valves. Circulator zone control with ZC and ZR terminals on R8182D,E,H,J. 8*Flame failure during the running cycle results in a 45 second attempt to restart. If unsuccessful, safety shutoff occurs, requiring manual reset before burner can be restarted. R8182D,E,F mount directly on burner; R8182H,J mount on 4 x 4 in. junction box and include 5 ft (1.5 m) armored capillary with remote sensor. C554A Cadmium Sulde Flame Detector and a 24 Vac thermostat required. SOURCE 1 PART NO. DESCRIPTION MOUNTING MLP $ S1-R8182D1079 HI LIMIT 10F FIXED, LO LIMIT 10F-25F ADJUSTABLE VERTICAL 1266.03 S1-R8182D1111 HI LIMIT 10F FIXED, LO LIMIT 10F-25F ADJUSTABLE HORIZONTAL 1266.03
