AlphaStat-Plus Programming
If the Adjustable Values from the factory are inappropriate for the installation (see included document
stating programmed values) then the unit needs to be programmed.
The programming access code is for distributor or installer use only, as using incorrect Adjustable Values
can cause inefficiencies in the system or cause damage to the system voiding the warranty.
Once new values are ‘stored’ they are permanently written into memory and will be retained when power is
removed.
Note: Immediately after reprogramming please fill out the ‘Installation Adjustable Values’ in the ‘System
Adjustable Values’ table in the user guide. (Page 6.)
These instructions refer to the small yellow letters/words under the buttons on the AlphaStat-Plus.
1. Enter the installer programming access code. Available from distributors.
2. Every 10 seconds the characters ‘PRG’ will flash on the display indicating programming mode.
3. The ‘HWC’ light will be on to indicate the number being displayed is the ‘Demand’ value.
4. The ‘Demand’ can be adjusted using the ‘+’ and ‘-‘.
* Press ‘NEXT’ to move on to the next value.
5. Now the ‘BioSafe’ light will be on to indicate the number being displayed is the ‘BioSafe’ value.
6. The ‘BioSafe’ can be adjusted using the ‘+’ and ‘-‘.
7. All the values are now entered. The values can be checked by simply pressing ‘NEXT’ to cycle
through all the values noting which light is on and what value is displayed (as per AlphaStat-Plus
Programming Table).
8. To store all the values in permanent memory press ‘STORE’ at any stage. The values will be written
to memory and the unit will exit programming mode and return to automatic operation. The unit will
also store the values and exit if no key is pressed for a minute while in the programming mode.
9. Fill out the ‘System Adjustable Values’ in the user guide. (Page 6.)
