DANGER
230 volts do not touch the electrical components or circuits.
CAUTION
Isolate the mains electricity supply before starting any work and observe all relevant safety precautions. Observe electro-static discharge precautions: do not touch the PCB circuit.
NOTE
This accessory must be fitted by a competent person. Failure to comply could lead to prosecution.
Wireless Commissioning & Signal Strength
NOTE
Before fixing the DIGISTAT+2RF to the wall it is recommended to first check the signal strength from that location. Wireless commissioning: after initial start-up, the colon, CH, and antenna symbols should be flashing on the LP10RF display.
Follow either
LED indicator shows different colours depending on signal strength (see table below)
LED Indication | Chevrons | RF Strength |
Green | 4 | Very strong |
Amber | 3 | Strong |
Red | 2 | Weak |
None | 1 | Very weak |
To cancel signal strength mode
Positioning the Digistat +2RF room thermostat
The Digistat is a radio frequency device that is very flexible for positioning as there is no need for hard wiring to the appliance. The device should be mounted in an open area, no closer than 30cm from metal objects, including wall boxes. Mount the Digistat+2RF on a wall that is not subject to direct sunlight or draughts, preferably on an inside wall, 1.5 meters above the floor. The Digistat+2RF must also not be directly influenced by radiators or other appliances giving off heat.
To check the signal strength on previously installed and paired units:
Follow either
LED indicator shows different colors depending on signal strength (see table below)
LED Indication | Chevrons | RF Strength |
Green | 4 | Very strong |
Amber | 3 | Strong |
Red | 2 | Weak |
None | 1 | Very weak |
To cancel signal strength mode
If you wish to change any of the Installer Options as shown in the table below, enter the Installer Options Menu from Auto mode by pressing:
simultaneously for 5 seconds.
Pressing
Installer Options | Function | Select Option | Default | |
02 | Freeze protection | On | Off | On |
04 | Low Set Point °C | 5 | High Limit | 5 |
05 | High Set Point °C | Low Limit | 32 | 32 |
06 | Delayed Start (Energy saving feature) | On | Off | Off |
10 | Valve protection | On | Off | Off |
11 | Valve protection time (Mins) | 1 | 5 | 3 |
12 | Application type | 0 | 1 | 0 |
13 | System Capability | 0 | 1 | 0 |
Freeze protection will switch on the heating if the room temperature falls to 5°C and will then control the temperature at 7°C even if the Digistat is in OFF mode. The Freeze Protection default is ON. To switch off the Freeze Protection mode enter the Installer Options Menu (Refer to Installer Options 02) and change to OFF. Press to accept.
Option 04 & 05 – Low and High Limit set points.
The user temperature set points defaults are High 32°C and Low 5°C, to change these limits enter the Installer Options Menu (Refer to Installer Options 04 & 05).
Option 06 – Intelligent Delayed Start (Energy saving feature)
The Intelligent Delayed Start is an energy-saving feature that automatically reduces the warm-up time for the heating system. If enabled, the start time should be set an hour earlier then the time you want the property to reach the set temperature. Intelligent Start will delay that start time, by an amount that it has been calculated based on the actual and set temperature. As the weather becomes milder, the start time is delayed, so that fuel is not wasted bringing the room up to temperature earlier than necessary. The Digistat calculates approximately 10 minutes to raise the temperature by 1°C, up to a maximum of 6°C.
NOTE
Intelligent Delayed Start only applies in Auto mode. Intelligent Delayed Start default is in OFF mode. To switch ON Intelligent Delayed Start enter the Installer Options Menu (see Installer Options 06).
NOTE
The Intelligent Delayed start option is not suitable for underfloor applications. Ensure Installer option 06 is set to OFF before final commissioning for underfloor application.
SPECIAL NOTE
If the Intelligent delayed start feature is enabled, (Off changed to On in Installer option 06), please inform the end user of this feature.
The following special note has been added to the user instruction to explain the adjustment requirement: When the delay period is operating as indicated by the flame symbol flashing, pressing any button returns the Digital to auto mode allowing normal button operation until the next time/ temperature event, when it will resume the delay start mode or follows the Holiday, Manual, Override, or Off modes as selected. Changes to the installer options and pre-set programs must be made with the flame symbol not flashing.
Option 10 – Valve Protection
In some heating systems, there may be a requirement to protect the system by operating it once a day, for a given period. If valve protection is selected the system will be operated for a period as shown in valve protection time (mins). Valve protection time is every day at 10.00 am. The valve protection default is OFF. To enable the valve protection mode enter the Installer Options Menu (Refer to Installer Option 10).
Option 11 – Valve Protection time (mins)
Valve protection time can be set between 1 and 5 minutes (default 3 minutes). To change this once a day on time enters the Installer Options Menu (Refer to Installer Option 11).
Option 12 – Application Type
Digistat+2RF can be used for different applications.
In the installer menu, select:
Option 13- System Capability
Adjust this setting to suit the heating system capability.
In the installer menu, select:
Display Error code E1
When the display shows an error code (E1) this indicates a sensor fault and the heating system will remain Off. Please contact your local heating service engineer to replace your Digistat +2RF.
