Relay operation while in error modes
1. Relays should turn off immediately whenever a Valve Error occurs.
2. Relays should remain on and continue to operate as programmed
if a MAV Error (1006/1007) occurs and the valve has already en-
tered regen.
3. Relays should remain off, and not operate as programmed, if a
MAV Error (1006/1007) occurs and the valve has not entered regen.
Can be used with DC voltage to power. When utilizing DC voltage, now has a low DC voltage display when voltage drops below
12.05 VDC at a pre-regeneration check. Contact manufacturer for further details.
