ZONE CONTROL
ZONE CONTROL BY VALVE:
Heating zones controlled by
zone valves will require a separate power supply for the
valve(s) with end switch(s) to complete the call for heat to
the Ascent Hydrostat control. A multi zone valve panel (EK
P/N: 10-1216, ZVC404 or equivalent) may also be used;
follow the instruction manual found with the control. The
control will need an end switch to connect to TT on the
Ascent Hydrostat control to complete the call for heat.
ZONE CONTROL BY CIRCULATOR: Zone control by
circulators requires a circulator relay with end switch (EK
P/N: 10-0464-4, SR504 or equivalent) or individual relays
(EK P/N: 10-0464, SR501 or equivalent) for each zone.
The boiler bypass circulator is still used in this case.
NOTICE: An additional tee must be installed into the
supply for each additional circulator. The tee is the supply
connection for any zone circulators with the returns for
these zones connected to the boiler return. See
“Zoning
with Circulators” diagram found in this manual.
