Control Overview—Valve Adapter Module
Valve Adapter Module—Valve Output [52][A1/M2/M3]: 24VAC or 120VAC Output
Applicable for Vitotronic 100, GC1, Vitotronic 300, GW2 and Vitocontrol-S, MW1
1 Black [52] plugs are pre-wired
to modules. Plug into socket
within control for specific valve
output to be controlled by
adaptor.
2 The 120VAC valve adaptor
identified by two relays on PCB.
3 The 24VAC valve adaptor
identified by two relays and
transformer on PCB. Terminals
on DIN rail inside control
junction box.
4 Modules are mounted onto DIN
rail located inside of control
connection enclosure.
5 Both modules have a single
wire which is terminated in
[156] terminal blocks, terminals
8, 9 or 10. This provides
120VAC power for the
operation of the module
adaptors.
6 The 120VAC valve actuator is
wired into output terminal block
of adapter. Wires connected to
the G/N/L2/L1 terminals.
7 The 24VAC valve actuator is
wired into output terminal block
of adaptor. Wires connected to
the Open/Close/Common
terminals.
