9.16 ASCSignal-NGC-Hub-AC

This page describes the device driver and the device window for the hub air condition system integrated in ASC Signal NGC 4000 ACU.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Shows all measurements as well as the climate control units state
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the controller.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• readBackDelay --- Delays the read back of a parameter actually set for at least the given delay time. This shall ensure that the device has processed the new parameter before it is read back. You should leave this parameter at it's default setting.

• highTempAlarm --- Defines the ambient temperatures high alarm limit.

• lowTempAlarm --- Defines the ambient temperatures low alarm limit.

• fan.setpoint --- Defines the temperature setpoint in '°C' for activating the fan.

• fan.diffSetpoint --- Defines the differential temperature setpoint in '°C' for how long the fan stays on.

• cool.setpoint --- Defines the temperature setpoint in '°C' for activating the a/c cooling.

• cool.diffSetpoint.1 --- Defines the differential temperature setpoint in '°C' for how long a/c cooling stays on.

• cool.diffSetpoint.2 --- Defines the differential temperature setpoint in °C for how long a/c cooling stays on

• heat.setpoint --- Defines the temperature setpoint in '°C' for activating the heating furnace

• heat.diffSetpoint.1 --- Defines the heating differential temperature setpoint in '°C' for how long heating furnace stays on.

• heat.diffSetpoint.2 --- Defines the heating differential temperature setpoint in '°C' for how long heating furnace stays on.

• loPressure.setpoint --- Defines the compressor low pressure alarm setpoint.

• hiPressure.setpoint --- Defines the compressor high pressure alarm setpoint.

• humidity.setpoint --- Defines the humidity cycle differential setpoint for how long furnace or cooling stay on.

• humidity.diffSetpoint --- Defines the humidity cycle setpoint

• unitA.voltage --- Defines the output voltage unit B.

• unitB.voltage --- Defines the output voltage unit B.

• switchoverTime --- Defines the auto switchover interval in fixed steps.

• compressorDelay --- Defines the compressor delay time in fixed steps.

• fanMode --- Defines the hub a/c fan mode.
