Output Wiring
Wiring of outputs depends on heat type configuration.
Heat1Type
Heat1Type always outputs on DO1 and AO4.
When using a floating valve, DO1 is used for opening the valve and DO2 is used for
closing the valve.
When the Pwm Triac option is used, DO1 is used to control the heating source.
Heat2Type
Heat2Type always outputs on DO2 and AO4 unless Heat1Type is a floating valve, in
which case the digital outputs are shifted (i.e. DO2 becomes DO3).
When using a floating valve, DO1 is used for opening the valve and DO2 is used for
closing the valve if Heat1Type is set to Analog.
When the Pwm Triac option is used, DO2 and AO4 are used to control the heating
source.
Wiring of outputs depends on the type of control signal used to drive the heating sources. For instruc-
tions on how to configure a controller’s outputs using the dc gfx Applications interface, see Configuring
the Preloaded Applications.
For screen-by-screen steps on how to configure a controller’s outputs using an Allure EC-Smart-Vue
sensor, see Setting up Outputs.
