Installation & Operation Manual

6. If no other changes are necessary, press the BACK button

to return to the Parameter List Screen.

7. Once all the necessary adjustments have been made,

press the BACK button to return to the Setup Screen.

8. Press the SAVE button to program all changes made to

the set points and return to the Status Screen. Leaving

the Setup Screen without pressing the SAVE button will

erase the changes made to the set points and change

them back to their previous settings.

The SAVE button must be pressed to ensure proper

programming of the controls. Failure to press the SAVE
button will require all changes to be reprogrammed.

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.
