Honeywell Thermostat L4006 User Manual

These boiler-mounted, immersion type controllers operate in response to temperature changes in hydronic heating systems. L4006A breaks the circuit on a temperature rise to the control setting. It is used for high limit or low limit control.
When used as a controller or as a low limit, a separate high limit must be used. L4006B makes the circuit on a temperature rise. It is used as a circulator controller, delaying circulator operation when boiler water temperature is below the control setting.

L4006E,H includes a trip-free manual reset switch. These models are designed to break the control circuit whenever the temperature of the controlled medium reaches the high limit setting. A reset button on the front of the case must be pressed to re-establish the control circuit. L4006H also includes bracket and clamp for surface mounting on pipe or tank. A plastic bag of heat-conductive compound is included with the L4006A,B,E AquastatÆ Controllers for use when the sensing bulb is inserted into a well designed for a large bulb than the one used on the L4006A,B,E. A 124904 Well Adapter, for use on old wells that do not fit the L4006A,B,E immersion well clamp, can be ordered; see form 68-0040, Wells and Fittings for Temperature Controllers.. A setting stop is included to prevent setting above a desired temperature on limit. If a well adapter or other accessories are needed, refer to form 68-0040, Wells and Fittings for Temperature Controllers, for part numbers and ordering information.

A type of water heater that works in response to temperature changes in a hydronic heating system.

The L4006A breaks the circuit when the temperature rises to the control setting. It is used for high or low control. When used as a control or low limit, a different high limit will be used. L4006B operates the circuit in the event of temperature rise. It is used as a distributor, delaying the operation of the distributor when the hot water temperature is below the control setting. L4006E,H includes a non-triggered manual reset switch. These models are designed to close the control circuit whenever the controlled fluid reaches a critical point. The reset button on the front of the case must be pressed to reset the control circuit. The L4006H also includes a bracket and clamp for mounting on a pipe or tank.

Honeywell Thermostat L4006 Feature

  • L4006, 7, and 8 provide Spst switching for high or low limit or circulator control.
  • L4006G includes two Spst switches that provide high limit and circulator control.
  • L4006,7; L6006,7 models are available for insertion in: vertical or horizontal immersion well, vertical or horizontal direct immersion, and surface mounting.
  • L4008, L6008 include remote bulb for mounting controller at a location away from the sensing element.
  • Totally enclosed Micro Switchô snap-acting switches operate on temperature rise to set point.
  • Models calibrated for high limit use are also suitable for low limit control if a separate high limit controller is used.
  • Visible control point scale and external adjustment screw, permit easy setting.
  • Remote bulb models may be used to sense air temperature in ducts and in outside air sensing applications.
