made to the two-pin connector labeled MAV located on the printed circuit board for PWSRTA control
valves. For valve types PWSRTA15 and PWSRTA2, a connection from a Watts No Hard Water Bypass
(V3097/ BSPT or V3098/ BSPT) to the two pin connector labeled MAV located on the printed circuit
board is required.
