Product Review

The AD1S is a replacement power head for Honeywell's V8043E normally closed 2-way zone valve with switch, it can also be used to replace Honeywell's V8043A (2-way valve without switch) equally well by simply not connecting the (red) switch wires. This powerhead is for use with Honeywell's new style valve bodies (series 6, removable head) only, and it includes the motor, housing, and 2 mounting screws.

The AD1S is 100% compatible to Honeywell part # 4000-3916-026 which is replacement powerhead for Honeywell's V8043E; and it is also 100% compatible to Honeywell part # 4000-3916-021 which is replacement powerhead for Honeywell's V8043A (simply not connecting red switch wires to anything or cut them off). However, the AD1S cannot be used to replace power-heads on Honeywell 3-way valves V8044E and V8044A.
