6.5.4 Setting Heating and DHW Time Schedule
When setting times for periods for which a heating circuit or DHW may operate, it is worth noting that
the times set will be subject to a variance if start or stop optimisation is turned on. If optimisation is
turned on, the operating times set will need to be the occupancy times of the building, as the
controller will turn on the heating to bring the room temperature up to set level in time for the 1st on
period. The default screen is displayed when the ESC button is pressed several times and the screen
displays "Cascade temp" or "Boiler temp"
The heating time schedule point can be altered by performing the following actions from the default
screen:
1. Press OK
2. Using the scroll wheel select appropriate circuit e.g. "Time Prog heating circuit 1" or "Time
program 4 / DHW".
3. Press OK
4. Set the desired day or week period required for time control to be active by pressing
OK and then using the scroll wheel to select appropriate period e.g. "Mon - Fri"
5. Press OK
6. Rotate scroll wheel and select "1st phase on". Press OK to change 1st time on with scroll wheel.
7. Press OK
8. Rotate scroll wheel and select "1st phase off". Press OK to change 1st time off with scroll wheel.
9. Press OK button
10. Repeat steps 6 - 9 for up to 3 periods of on and off times.
6.5.5 Setting the Hot Water Temperature
The DHW set point can be altered by performing the following actions from the default screen:
1. Press the OK button
2. Using the scroll wheel select "Domestic Hot Water", press OK
3. Press OK , the temperature should now be flashing. Use the scroll wheel to set desired
temperature, press OK
