Enter an offset
value for the auxiliary relay. This screen is not used
if step 26 is set to TIMECLOCK. (SZ1064 only)
Auxiliary Relay differential Screen.
Enter a dif-
ferential value for the auxiliary relay. This screen is
not used if step 26 is set to TIMECLOCK. (SZ1064
only)
Auxiliary Relay output Screen.
Choose
whether the auxiliary output will be used for either a
TIMECLOCK output, a stage of HEAT or a stage of
COOL. (SZ1064 only)
time Clock output Screen.
Choose whether the
auxiliary output will be OPEN or CLOSED during
occupied periods. This screen is not used if step 26
is set to HEAT or COOL. (SZ1064 only)
3-Pipe Fan Coil enable Screen.
Choose YES if
using a three-pipe system. Otherwise choose NO.
If YES is selected, skip to step 42.
2-Pipe Fan Coil enable Screen.
Choose YES
if using a two-pipe system. Otherwise choose NO.
If NO is selected, and skip to step 42 and it is
assumed to be a four-pipe system.
digital Aquastat input Screen.
Choose whether
DI1 will be normally open (N.O.) or normally closed
(N.C.) for cooling. The next screen is skipped.
Analog Aquastat input Screen.
If an analog aqua-
stat is selected, choose the changeover setpoint to
distinguish when hot or cold water is available. If
the 'pipe' temperature is below this setpoint, analog
output 2 will do cooling. If the 'pipe' temperature is
above this setpoint, analog output 2 will do heating.
(SZ1064 only)
modulating output 1 Proportional Band Screen.
Enter the number of degrees away from the heating
setpoint that the valve will be fully open.
modulating output 2 Proportional Band Screen.
Enter the number of degrees away from the cooling
setpoint that the valve will be fully open.
modulating 1 Setpoint offset Screen.
Enter an
offset value for modulating output 1. This is the
number of degrees below the heating setpoint
before the output begins to modulate.
modulating 2 Setpoint offset Screen.
Enter an
offset value for modulating output 2. This is the
number of degrees above the cooling setpoint
before the output begins to modulate.
modulating 1 output Action Screen.
Choose
whether modulating output 1 will be direct or
reverse acting.
modulating 2 output Action Screen.
Choose
whether modulating output 2 will be direct or
reverse acting.
