4.2.3.4. Close the log and iClone interface. The controller is now ready to use.
Note:
The controller’s parameters have to be adjusted further depending on the system’s behaviour
during commissioning. This software is an initial configuration file.
4.2.4. General operation
To set other settings through controller’s control panel if necessary, follow the user guide provided
for EPC3008 from the page below:

controllers
4.3. Timers settings
The T1 timer starts when the SpiraHeat
TM
is set to run. The T1 timer relay opens the main isolation
valve prior to starting the EPC3008 controller. This allows the control valve to warm up and reduces
the risk of water hammer.
T1 must be set to a value below T2. By default this is set to 50 seconds.
The T2 timer starts when the SpiraHeat
TM
is set to run. The EPC3008 will close the isolation valve
when the control signal to the control valve is below the Alarm Control Point, A1.HI (default 1%). The
T2 timer relay allows the control valve to open over the Alarm Control Point before returning control
of the isolation valve to the EPC3008.
T2 must be set to a value above T1. By default this is set to 60 seconds.
