Auxiliary Delay
When CFH signal is "ON" the relay contact of the A1 Auxiliary module stays closed. When the CFH signal
changes to "OFF", the contacts of the relay stay closed as long as the delay is set up.
The AUX contacts operate on a delay after CFH.
AUX turnoff range is 0 to 600 seconds. The default value is 180 seconds.
INSTALLERS NOTE: If the end user requires the "System Pump" to be turned off if the "CFH" or "Safety" signal
is removed, it is recommended that the system pump be operated from the "Aux 1 Relay", to provide a delay on
turn off.
NOTE: If the "Call-for-Heat" (CFH) or "Safety"
signal is removed from the Y-200, the pump delay
will time out and open the auxiliary contact.
