Graph Enabled Display Legend

This displays a graph of temperature vs time with a default period of 7 days. This can be changed by selecting the Show graph checkbox in the Settings. This will show an interface like the following:

Mounting the RAPT Temperature Controller

The RAPT Temperature Controller offers a number of different mounting options offering the versality to be able to change how to controller is mounted depending on what you are using the controller for. The controller is provided as standard with a mounting plate which is installed onto the controller out of the box. This mounting plate can be removed if you would instead prefer to mount the controller onto the wall for example.

Removing the Mounting Plate

To remove the mounting plate, slide the mounting plate down towards the bottom of the controller.

Wall Mounting Option 1

If you prefer to mount the RAPT temperature controller to your wall however you did not want to damage the wall by screwing into it you can attach the mounting plate to the wall using strong double-sided tape and then slide the RAPT temperature controller onto the mounting plate to secure it.

Wall Mounting Option 2

Screw two screws into the wall using the following template as a guide. Then simply hook the controller onto the screws using the mounting points provided on the back of the controller.

Please use this link to download and print the RAPT Temperature Controller Drill Mounting Template

Wall Mounting Option 3

Unscrew the hanging hook and rotate it 180 degrees, retighten and attach the controller to the wall using this hanging hook. This can be mounted to your wall using a screw or hanging the controller onto a hook which is already mounted on your wall for example

Wall Mounting Option 4

Another option for mounting the RAPT Temperature Controller onto a wall is to drill a screw through the recessed holes below the front face plate which continue all the way through to the two mounting holes at the back of the controller.

These holes can be identified by running your finger along the face plate in the area shown below. You can then either peel away the face plate and use an 8G x 60mm countersunk screw or you can drill straight through the face plate using an 8G x 60mm or 10G x 60mm countersunk screw as shown below:

Vertical Bench/Panel Mounting

WARNING: Ensure the temperature controller is unplugged from the wall socket before changing the orientation of the cables

If you want to neatly mount the RAPT Temperature controller vertically onto your bench or into a custom designed cabinet/panel for example, the orientation of the cables can be quickly and easily rearranged. To achieve this, undo the 4 screws which hold the front and back housings together and then pull the two housings apart.

Unscrew the two screws which hold the slotted blanking plate to the housing and remove the slotted blanking plate.

Move the cable glands to the back of the unit and secure in place with the slotted blanking plate, then secure the slotted blanking plate to the housing using the two screws. Then reassemble the front and back housings and secure with screws

You can then custom design your own panel or cabinet to mount this temperature controller into with the outlets and wiring now exiting out the back of the controller allowing for a very neat mounting arrangement.

Alternatively, if you want to mount this on your bench top or on top of your Temperature Controller you can use the mounting plate as a stand to keep the temperature controller in an upright position. Simply slide the temperature controller housing onto the guides on the mounting plate as shown:

Temperature Probe Calibration

The RAPT Temperature Controller comes as standard with a 2m extension temperature probe. This probe is calibrated out of the box. You may wish to calibrate this for a number of reasons such as to improve accuracy around the temperature range in use, or if you have replaced the original temperature probe for any reason.

To calibrate the temeprature probe:

1. Enter the menu by pressing Select
2. Set up two glasses of water. Ice water to one glass and add hot water to the second glass

3. Use the Up or Down arrows to navigate to Settings and press Select
4. Navigate to Calibration Point 1 and hit Select

Calibration Point 1

Insert the temperature probe of the RAPT Temperature Controller into the glass of ice water while simultaneously measuring the temperature of the ice water using a calibrated external thermometer such as a digital instant read thermometer (KL23320). Wait for the temperature reading on both the RAPT Temperature Controller and the external calibrated thermometer to stabilise as much as possible.

Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature measured on the external calibrated thermometer.

Press Select to lock in Calibration point 1 and move on to Calibration point 2.

Calibration Point 2

Insert the temperature probe of the RAPT Temperature Controller into the glass of hot water while simultaneously measuring the temperature of the hot water using a calibrated external thermometer. Wait for the temperature reading on both the RAPT Temperature Controller and the external calibrated thermometer to stabilise as much as possible.

Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature measured on the external calibrated thermometer.

Press Select to lock in this calibration point 2

Alternatively, Bonding a RAPT Pill Hydrometer via Bluetooth and using this as the tmperature probe is ideal as this unlocks the ability to have powerful, customised Fermentation Profiles with steps that can be triggered by temperature, time, gravity and rate of change of gravity!

Reset Temperature Probe Calibration

In the event that you revert back to the standard probe that is preinstalled in the RAPT Temperature Controller, you can manually reset the temperature probe to the default settings.

1. NTC beta: 3950

2. NTC ref. temperature: 298.2

3. NTC ref. resistance: 100000

You can also select Forget Calibration in Settings. This will revert any saved calibration settings to default.
