4.2 Preparing for Installation
- Disconnect Power: Ensure the electrical supply to the installation area is completely switched off at the consumer unit/fuse box.

4.3 Electrical Connection
The C4HTR requires a 240V electrical supply. Wiring should be performed by a qualified electrician.
- Identify the Live (L), Neutral (N), and Switched Live (T) terminals on the fan unit.
- Connect the mains Live (L) to the fan's Live terminal.
- Connect the mains Neutral (N) to the fan's Neutral terminal.
- For timer and humidistat functionality, connect a switched live supply (e.g., from a light switch) to the fan's Switched Live (T) terminal. This allows the fan to activate when the light is switched on, or to override the humidistat.
- Ensure all connections are secure and correctly insulated.

4.4 Securing the Fan
- Position the main fan body into the prepared opening.
- Secure the fan body to the wall/ceiling/panel using the provided screws and wall plugs.
- Once the main body is secure and wired, reattach the front cover by aligning and twisting until it clicks into place.
5. Setup and Adjustment
The C4HTR fan features an adjustable humidistat and timer. These settings are typically accessed by removing the front cover.
5.1 Humidistat Adjustment
The humidistat controls when the fan activates based on the room's humidity level. It can be adjusted to suit your environment.
- Locate the humidistat adjustment dial or screw on the fan unit (usually behind the front cover).
- Turning the dial towards a higher setting (e.g., 'Max' or a higher percentage) means the fan will only activate at higher humidity levels.
- Turning the dial towards a lower setting (e.g., 'Min' or a lower percentage) means the fan will activate at lower humidity levels, running more frequently.
- Adjust incrementally and observe fan behavior over a few days to find the optimal setting for your needs.
5.2 Timer Adjustment
The timer controls how long the fan continues to run after the switched live supply is turned off (e.g., after the light is switched off) or after the humidity drops below the set point.
- Locate the timer adjustment dial or screw (often labeled 'Timer' or with time increments).
- The timer can typically be set from a few minutes up to 30 minutes.
- Turn the dial to increase or decrease the run-on time as desired.
6. Operating Instructions
The Xpelair C4HTR fan operates automatically based on its humidistat and timer settings, or manually via a switched live connection.
6.1 Automatic Operation (Humidistat)
- When the ambient humidity level in the room rises above the set point on the humidistat, the fan will automatically switch on.
- The fan will continue to run until the humidity level drops below the set point, after which it will run for the duration of the set timer.
6.2 Manual Operation (Switched Live)
- If connected to a switched live supply (e.g., room light switch), the fan will activate when the switch is turned on.
- When the switch is turned off, the fan will continue to run for the duration set on the timer.
6.3 Speed Settings
The fan offers two speed settings for airflow:
- Speed 1: 15 litres per second (L/s)
- Speed 2: 21 litres per second (L/s)
Refer to the installation guide or consult a qualified electrician for instructions on how to select the desired speed setting, as this may involve internal wiring adjustments.
