HYD Outputs

Description

HYD applications can have a variable number of heating and cooling stages. The number of pipes used on the unit could be two or four. The outputs could be of staged, PWM, floating, or Thermal type. In addition the outputs can be of Change over mode.

Purpose

Define the operation of the hydronic controller outputs and the type of equipment to be controlled.

Mode

Configuration can be performed with the wizard Off-line or On-line.

Procedure

Click the Outputs button on the left pane to open the Output Configuration page.
Enter information into available fields.
Click Commit to save the settings or Reset to revert to the last saved settings.
Click Next to display the Input Configuration page.

Fields

Name	Definition
Types	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. Output 2- Mode Output triac pair connected to terminals 16/17/18 of the controller. Select the control sequence option to be allocated to output 2. For four-pipe applications, always allocate this output to the cool option to minimize field wiring errors. For two-pipe applications, you can select only the changeover option. Output 2- Type Selection options are the same as for Output 1.
