Set Hot Water Generator (HW) operation
Verify HW circulator mode
The HW Mode is programmed to heat an indirect hot water
tank. When a tank thermostat or a tank sensor initiates a call
for heat, the SMART TOUCH control will turn on the HW
pumps and turn off the boiler pumps (if running). If the
system pump is running, it will remain on. When the HW
call for heat ends, and there is no space heating call for heat,
the HW pumps will continue to run for a period of time.
This pump delay is set at the factory to 30 seconds. If a
shorter or longer delay is desired, the appropriate parameter
in the control must be changed. See the SYNC Service
Manual for a detailed explanation of this procedure. If there
is an active space heating call for heat, then the boiler pumps
will be turned on and the HW pumps will be turned off.
Set HW target temperature
When in the HW Mode, the control will modulate to
maintain the outlet temperature to a set point. This set point
is set at the factory to 180°F. If a different set point is desired,
the appropriate parameter in the control must be changed.
See the SYNC Service manual for a detailed explanation of
this procedure.
Set clock
To program the clock, access the night setback parameter by
pressing the following buttons:
The SMART TOUCH control has a built-in clock that it uses
for its night setback feature and for logging events. This clock
must be set when the boiler is installed, and anytime the
boiler has been powered off for more than one month. Use
the following procedure to set the clock:
1. To set the clock, press the SELECT button in the upper
right-hand corner of the display. The date and time are
displayed as “Day dd/mm/yy hh:mm”. Day = day of the
week (1 = Monday, 2 = Tuesday, etc.), dd = date, mm =
month, yy = year, hh = hour, mm = minutes (24 hour
time; 2:30PM = 14:30).
NOTICE
The internal clock does not adjust for
Daylight Savings Time and therefore, will
require a manual adjustment.
Configuration of the cascade
When installed in a Cascade system, the individual controls
must be programmed for cascade operation. To program the
cascade parameters, access the Cascade Menu found in the Setup
Menu by pressing the following buttons:
Note:
The CASCADE button on the Main Menu will only
display the current status of the cascade.
1. Once in the Cascade Setup Menu select the appropriate
parameter by pressing the SELECT button.
2. The first time the cascade setup parameters are accessed,
you will be required to enter the service password. Enter the
service password as described in the SYNC Service Manual.
3. Once the password has been entered correctly, the
Parameter Change Screen will appear. The Parameter
Change Screen will display the parameter being changed,
the previous setting of the parameter, and adjustment
buttons.
4. To adjust the parameter, press the + or - buttons to change
the value being displayed.
5. Make the correct adjustments and then press the APPLY
button.
6. Once all the parameters have been adjusted press the BACK
button. This will return you to the Setup Menu.
