Honeywell Powerhead 40003916-003/U

The Honeywell 40003916 Powerhead enables a complete powerhead to be replaced without the need to drain down the V4043, V4044 and V4073 valves. On older valves which pre-date 1985 the head cannot be replaced, the adaptor plate assembly can be used to upgrade the valves which in turn allows the replacement powerhead to be fitted.

Features and Benefits:

  • One type of powerhead for the separate valve series.
  • No need to drain down the valve.
  • Suitable for use with V-series Honeywell valves.

    Having had to replace the powerhead I bought elsewhere after only 2 years I decided to buy the original equipment which had lasted most of the last 20 years. It is important to understand how this unit works. It is intended to stall in the mid-way position to give hot water and heating and in the full travel position for heating only; this is made possible by the micro-switches reduce power when both heating and hot water are required.
