INSTALLATION

The OUH3-DT thermostat can be used with its internal air sensor or if required with an optional remote air sensor or optional remote black bulb sensor.

CHOOSING A LOCATION FOR YOUR OUH3-DT OR REMOTE SENSORS
The OUH3-DT controller or sensors should be mounted on an internal wall approximately 1.5 meters from floor level and should be in a position away from draughts, direct heat and sunlight.
If you decide to use remote sensors you will need to change “A4” to “N2” on the master / default settings. See page 7 for more information.

INSTALLING THE OUH3-DT CONTROLLER

• Decide if it is easier to drill holes for cable glands or conduit in the enclosure before mounting to the wall.
• Screw the OUH3-DT in position using suitable fixtures and fittings allowing space to the right to access the control switch.
• There are 4 holes in the corners of the case, or you can drill additional holes in the back below the circuit board.

1. Wire the controller as per picture above, making sure all the terminals are done up tightly.
2. If you are using a remote sensor connect to terminals 5 and 6 (marked NTC). These are positioned on the thermostat mounted on the front cover. You can use any insulated copper wire. Polarity of the sensor does not matter. (you will also need to change the default settings to activate the remote sensor see page 7).
3. Please also read the heater instructions regarding connection as it gives details on wires sizes etc.

SWITCH MODES

• The switch on the right hand side of the controller has the following modes:

• OFF – When in this position both the fan and the heat are turned off.
  Please Note: – Should you have a frost thermostat fitted to the heater it will still operate even with this switch in the off position.

• FAN – When in this position the fan will operate regardless of the thermostat settings. Useful in the summer for moving air around.

• HEAT – When in this position the heater will turn on and start warming up the building BUT only when the thermostat is asking for heat. It will not over-ride the thermostat settings.

CHANGING THE MASTER / DEFAULT SETTINGS.

There are various master / default settings that can be changed by entering the default settings. To enter these settings, turn off the thermostat by pressing the button. Then press and hold the button for 3-5 seconds until the A1 appears on the screen. You are now in settings mode and if you don’t press any button for 5 seconds the display reverts back to off mode. Press button to switch to next option and press or buttons to adjust the data. If you wish to exit the settings without waiting 5 seconds press the button.

USING AS A CONVENTIONAL THERMOSTAT.

It is easy to set up your OUH3-DT thermostat to operate as a simple, conventional thermostat without the need to programme different times and temperatures. There are 2 steps.

1. Set the temperature required – Refer to “Run Modes” on page 3 and use manual mode, then select the required temperature by using the or buttons.
2. Lock the thermostat – Refer to “Locking the controller” on page 3. Locking the thermostat will disable all the buttons except the on/off button. If you want to disable the on/off button as well, you will need to change the default lock settings before starting this process (see section 5).

SENSOR FAULT CODES.

• E1 or E2 fault codes are displayed if the temperature sensors are faulty or are not connected. The thermostat will stop heating until the fault is corrected.
• E1= Internal sensor faulty.
• E2 = External sensor faulty or missing / not present.
• If in the master settings shown overleaf, you have selected N3 for option A4 (Sensors used) you will get a fault code and the thermostat will not work, please select either N1 if you are using the internal sensor or N2 if you are  using an external mounted sensor.

FUSE.

• There are no serviceable parts inside but before removing the cover to the controller make sure you have isolated all sources of power.
• Please Note: There may be more than one power source entering the enclosure.
• The thermostat is protected by a 3A fuse but this is positioned in the heater it attaches to. (See heater instructions for more information)
