INSTALLER OPTIONS
(Option 04) Maximum Setpoint Limit
Change maximum setpoint temperature. After any changes to
setpoint limits, all setpoints in AUTO, MANUAL, BOOST and
HOLIDAY modes will be modified to conform accordingly.
To make changes to the default Installer Options shown below,
enter the Installer Options menu by pressing the settings
button for 3 seconds. This allows access to the User Menu
01, the Advanced User Settings Menu 02, the Installer Settings
03, and Service Interval Settings 04. Use the + and - buttons to
scroll to Installer Options and press O to select. You can exit
the menu by pressing until you have returned to the home
screen. In the Installer Options menu (Fig 8), scroll through
the options using the + and - buttons and press O to select.
Scroll through the different settings using the + and - buttons
and press O to select and save. (Fig 9 shows Option 02 OFF).
(Option 05) Optimum Start
When enabled, this uses current ambient temperature, the next
scheduled setpoint and heat gain data captured by the device to
adjust the thermostat setpoint early, so the ambient temperature
is at the required level when the next event starts.
Delayed Start
When enabled, this uses current ambient temperature, current
event setpoint and heating characteristics of the environment
to delay implementation of the setpoint if the ambient
temperature is already close to it, therefore saving energy.
(Option 06) Valve Protection Time
In some hydronic heating systems it may be required to protect
the valve by operating it for a given time. When enabled, this
maintenance feature ensures that each relay output is operated
for at least one (1) minute each week.

(Fig 9)
(Option 07) Sensor Fault Function
(Option 01) Partial Sight Assistant
In the event of a sensor fault, central heating output is reduced
to 30% by turning heating ON for 3 minutes, then OFF for 7
minutes.
When enabled, audible tones indicate when the setpoint is
more than, less than or equal to the current room temperature
when a user manually adjusts the setpoint using the + button:
Setpoint > room temperature - single high tone per 0.5°C
increase
(Option 08) Application Type
Select the central heating system energy type.
Setpoint = room temperature - double tone
Setpoint < room temperature - single low tone per 0.5°C
decrease
(Option 09) System Capability
Select the flow capability of the heating system.
(Option 13) Installer Settings Lock
(Option 02) Frost Protection
When enabled, installers can lock the installer settings menu
until a 3 digit code is entered. If the code is forgotten while
device is locked, please call the Technical Helpline.
The Digistat will switch on the heating if the temperature falls
to 5°C and maintains a temperature of 7°C even when
in OFF mode.
(Option 20) Reset (Service Interval settings are NOT reset)
Reset the Digistat to its original factory settings.
(Option 03) Minimum Setpoint Limit
Change minimum setpoint temperature. After any changes to
setpoint limits, all setpoints in AUTO, MANUAL, BOOST and
HOLIDAY modes will be modified to conform accordingly.
Service Interval Options continued on reverse.
