There are two possible ways to select the SCHEDULE to be initiated. Schedules can be
selected internally or externally.
INTERNAL: If EXTENDED FUNCTION, SCHEDULE SELECT [SS] is set to
INTERNAL [00], use Push Button switches (20) and (21) to select the desired
SCHEDULE. Push Button switch (21) increments the 10's digit by one and Push Button
switch (20) increments the 1's digit by one. When the maximum number is reached for
either digit, that digit resets to zero.
EXTERNAL: If EXTENDED FUNCTION, SCHEDULE SELECT [SS] is set to
EXTERNAL [01], use the binary combination of TS1-FS7/SS1, TS1-FS11/SS3, to
select the desired SCHEDULE (See section 5.3 CUSTOMER TERMINAL STRIP
CONNECTIONS and EXTENDED FUNCTIONS section 7.3.

: Push Button (12), LEDs
(7-11 & 13-18).
Using Push Button switch (12) any function can be selected. Use Push Button to shift the
lighted (active) selection down one LED. If no LED is lit, then EXTENDED FUNCTIONS
have been selected. This is necessary when programming the EXTENDED FUNCTIONS
(See section 7.3 EXTENDED FUNCTIONS). EXTENDED FUNCTIONS can be reached
simply by pressing Push Button (12) until all the LEDs (7-11 & 13-18) are off.
