3.6 Mode (or Menu) Structure
There are 3 main modes (or menus) on the device –
Setup and Advanced Configuration Mode.
• User Mode - the live screen used for normal op-
eration. The process variable can always be seen in
this mode
• Setup Mode – allows access to the most important
parameters
• Advanced Configuration Mode - access all param-
eters via sub-menus
Setup Mode - press & .
Advanced Configuration - press & .
Never connect the instrument’s configuration
socket directly to a USB port as it will damage
the controller.
3.7 Returning to Operator Mode
Press & to move back one level

3.9 Use of the Controller for Non-
Temperature Applications
In the majority of applications this controller will be
used for temperature sensing, either via a sensor or a
linear DC input, which use heat and cool. However this
controller can be used for other types of processes.
If your process is not a temperature then the param-
eters labelled as “HEAT”refer to reverse acting outputs
used to increase the process value and “COOL” to de-
crease the process value.
As an example you may have a system that reads and
controls humidity. The “HEAT” output drives the hu-
midifier and the “COOL” output drives the de-humidifi-
er. Use the “HEAT” parameters to control the humidifier
and the “COOL” parameters to control the de-humid-
ifier.
Often the “HEAT” and “COOL” is referred to as “Pri-
mary” and “Secondary” on other controllers.
3.10 Controller Transmitter Function
The Standard 1020 & 1030 model can be used as a
“transmitter” to retransmit the process value or con-
troller setpoint via Output 3, if the linear option is fitted.
The parameter Usage in the Linear Output sub-menu
can be set to PV Retransmit or SP Retransmit.
In the Display menu, the parameter Transmitter can be
used to enable Transmitter view. This hides the Set-
point from view.
Control functions will remain active if
they have been configured.
