Page 5: Introduction
Introduction The CCR30 combines a Humidifier, a Dehumidifier and a radio control system into one unit, actuated by signals from Hanwell Temperature/RH telemetry units. • Both the humidity set point and the required dead band are adjustable by the user.
Page 6: Installing
Siting the CCR30 Location The CCR30 should be stood on either a solid floor or a secure shelf. It should never be positioned above or below anything of value. There are two holes in the back panel to allow the unit to be secured firmly: no weight should be taken on these, they are purely to prevent toppling.
Page 7: Connecting The Water Supply
In order for the system to function, there must always be a supply of tap water in the Feed Tank and the Drain Tank must not be completely full. If the Feed Tank runs dry or the Drain Tank is full a float switch will operate and the CCR30 will switch off until the problem is rectified.
Page 8: Connecting The Power Supply
The sump tank must be fitted below the CCR30 unit, e.g. under floor, or behind a wall sitting on a shelf directly under the CCR30. However the waste pipe from the CCR30 must not be kinked or run uphill in order to get to the sump tank.
Page 9: Connections On The Pcb / To The Ocb
Connections on the PCB / to the OCB The power connection from the mains terminal block to the control PCB is pre-wired. However the connection details are included in the diagram (Figure 2) below for your reference. The mains in cable fitted should be in accordance with Electrical rules and regulations and be capable of supporting a 1.5KW electrical load.

55% and the deadband is set to +/-3%. The CCR30 has been designed to work with a local sensor unit to ensure reliability of radio reception regardless of the position of the receiver, and without an obtrusive aerial.

Otherwise the red Led will stay on close to full time as the modem continues to attempt network logon. Running the software on a machine that is also running another Hanwell USB application may cause erratic results as the USB Drivers are shared, shut down the other application.

ON. See example (right, white square indicates switch position). Setting RH set Point The RH Set Point is the Relative Humidity value the CCR30 required, within the possible range 10% to 80%RH. The factory default set point is 55%. Example...
Page 13: Setting The Sensor Id
Setting the Sensor ID The Sensor ID is the station number of the telemetry sensor which is intended to control the CCR30. Once set, the CCR30 will only receive signals from that sensor. This is set using binary code. Example To set the Sensor ID to 105: 1.
Page 14 • If the RH reading is below the RH setpoint + deadband, the Humidifier will come on (indicted by LED D8). Air will be drawn through the front vent and expelled, with the addition of water vapour from the steamer, from the top vent. •...
Page 15: Maintenance
Maintenance The CCR30 should be regularly maintained to ensure optimum operation. Regular checks are particularly important in hard water areas where it is essential that adequate water filtering is provided. The following schedules are recommended. Monthly Maintenance It is advisable to check the unit on a monthly basis to ensure the unit is operating safely and is leak free.

Replace the tank unit cover making sure that the Earth lead does not become trapped (it should lie between the 2 Tanks). 10. Turn the power back on to both the Tank Unit and the CCR30. Normal operation (see section 2.2) will resume as soon as a radio signal is received.
Page 17: Humidifier Steamer Operation Maintenance
The Steamer PCB is mounted on the CCR30 PCB, accessed via the left hand panel. The steamer Cylinder is mounted next to the humidifier in the main area of the CCR30. It is accessed via the front panel of the CCR30.

Steamer operation will stop. Resolve the problem. If the alarm condition is listed as automatic, the unit will be automatically rest. If the alarm condition is listed as manual, reset the steamer by switching off the CCR30 then restarting it. •...
