C. LOW VOLTAGES RELAY OUTPUTS:
All Three low voltage relay contacts are rated 1AMP maximum @ 30VAC
maximum.
a. "X1" LOW STAGE "Y" RELAY (Contact X1):
i. The LOW Stage Y relay activates upon detecting a call for “Y1” (with or
without “ O ” active).
ii. Upon activation, the X1 terminal connects to "R" (the 24VAC powering the
DCC7235). This relay is NOT DRY; i.e. its pole is permanently connected to
“R”.
b. "X2" High Stage "Y" RELAY" (Contact X2):
i. The HIGH Stage Y relay activates on a call for Y2 (with or without “ O ” active.
ii. On activation, the X2 terminal connects to "R" (the 24VAC powering the
DCC7235). This relay is NOT DRY; i.e. its pole is permanently connected to
“R”.
c. “Z” RELAY" (Contacts Z1, Z1p):
i. The Z1 terminal switches to Zp on any “W” call (W1 or W2).
ii. As shipped, SHUNT H2 connects Zp to "R", i.e. THE W RELAY
CONTACTS ARE NOT "DRY" AS SHIPPED. See diagram below.
iii. WHEN H2 is removed the contacts are " DRY" and be connected to a
second, separate, isolated 24VAC power source. See diagram below.
