HYD
Select the hardware version to be used for the controller. Each hardware version has different combinations of inputs
and outputs. The software checks Type against the controller's selected application so that you cannot configure a
controller for an application that it cannot perform.

System
Define the type of equipment (number of pipes) being controlled.
TWO_PIPE
Unit has only two pipes. Selecting this system type limits the controller to control only one valve output and operate in
a changeover mode. When operating in changeover mode, the controller uses only the one valve for controlling both
heating and cooling. Use this configuration only when changeover operation is required.
FOUR_PIPE
Unit has four pipes connected, providing both heating and cooling at the same time. The controller uses one output to
control heating only and one output to control cooling only (as specified in Control Outputs).
Control
Outputs
Configures the two control outputs for the different type of actuators and control sequences required for the application.
Output 1- Mode
Output triac pair connected to terminals 13/14/15 of the controller.
Select the control sequence option for output 1. For four-pipe applications, always allocate this output to the heat
option to minimize field wiring errors. For two-pipe applications, you can select only the changeover option.
HEATING
The output is modulated open when heat energy is needed in the space.
COOLING
The output is modulated open when cool energy is needed in the space.
CHANGEOVER
The output is modulated open when heat or cool energy is needed in the space.
OUTP_NOT_USED
The output is not controlled by the controller and is always off.
Output 1- Type
Select the type of actuator to be connected to the output.
FLOATING
Three-point actuator that can be commanded open or closed (terminals 14/15 and/or 17/18). The run-times for the
actuator are configured on the Equipment Control tab (Output Options).
FLOATING_MID
A three point actuator that can be commanded open or closed on terminals 14/15 and/or 17/18. The run-times for the
actuator are configured in the Outputs tab. The Zero Energy Position (no Heat and no Cool) is the middle Position
(50%). The Cool Range is 0 to 50%; the Heat Range, 50 to 100%. The Range can be reversed by selecting the
Actuator Direct or Reverse Option. During the Synchronization Process, the fan is turned off.
PWM
Duty-cycled output where the 24VAC output is pulsed on/off in the duty cycle range 0% to 100%. This type drives
output terminal 14 and/or 17.
ONE_STAGE
Single-stage on/off output that switches terminal 14 and/or 17.
TWO_STAGE
Two-stage output: Terminal 14/17 is switched for stage 1 and terminal 15/18 is switched for stage 2.
THREE_STAGE
Three-stage switched output. Terminal 14/17 is switched for stage 1, terminal 15/18 is switched for stage 2. Both
terminals 14+15 and/or 17+18 are switched for stage 3.
THERMAL
Switched on/off output for switching a 24V thermal actuator on terminal 14/17.
