Honeywell Y plan 1 three-port mid-
position valve
The operation is identical to the S plan but it uses
a single three-port or mid position valve.
If a system has been set up
and the relays are moved
to a new function, the relay
binding must be cleared or it
will continue to carry out its
original function.
