For controllers with dual action output Y1
(example: Heat-Cool), an extra output Y1F with
Relay is available for the cooling action. If a
continuous output is desired for cooling, use
the retransmission output Y4 (option) configured
for retransmission of the signal: Y1F (cool).
Possible combinations for Y1 dual are:

For Y1 cool, R is the extra relay of Y1, while
C is the retransmission output Y4 configured
to retransmit Y1 cool: 4...20mA or 0...10 Volt.
Two normally open interlocked relays
(Switch actions increase, stationary,
