This option allows you to choose which sensor is used to control the heating system .
· Floor (default): With this setting, the floor sensor controls the heating system .
· Room/Floor Limit (advanced): With this setting, the room sensor controls the heating system subject to maximum and minimum limits for floor temperature . The maximum temperature limit protects wooden floors from excessive heat . The minimum temperature limit prevents the floor from becoming uncomfortably cold when heating is not needed, e .g . in a bathroom . Note that this function will increase energy consumption . Floor Limit temperatures are set in the “Temperature Scale” menu .
· Room: With this setting, the room sensor inside the thermostat controls the heating system .
Maximum temperature depends on floor type and temperature scale .
1 . Tap the “Menu” button on the home screen . 2 . Then tap the “Engineer Settings” button . 3 . Tap the “Sensor Application” button . 4 . Confirm that you want to set the Sensor Application . 5 .

PAGE 51
© 2023 OJ Electronics A/S

This option allows you to set the minimum and maximum temperature to which the thermostat can be set as well as the minimum and maximum limits for floor temperature .
Operating temperatures:
· Minimum Temperature Scale can be set between 5°C and 15°C . · Maximum Temperature Scale can be set between 20°C and 40°C .
(If “Sensor Application” is set to “Floor”, a maximum temperature of 27°C can protect wooden floors from drying out . For precise information, please ask your flooring supplier) .
Floor limit temperatures:
Floor limit temperatures allow you to set the lowest (Minimum Temp . Limit) and highest (Maximum Temp . Limit) permissible floor temperature during normal room temperature control . If floor temperature drops below the Minimum Temp . Limit, the thermostat will activate the heating system to maintain the temperature above the set minimum . If floor temperature rises above the Maximum Temp . Limit, the thermostat will deactivate the heating system to maintain the temperature below the set maximum . Floor Limit temperatures are only available if “Room/Floor Limit” has been selected under “Sensor Application” .

EN50559 1/2
This thermostat complies with EN 50559 (VDE 0705-559) for electrical floor heating . The regulation applies to electrical floor heating, with a maximum floor weight of 4 kN/m² . To ensure that hotspots due to unintentionally covering up the surface are avoided, the heating function can be time-limited as per EN/DIN .
Note that this function is not applicable to other heating applications such as wall and/or ceiling heating
If it can be foreseen in advance that unintentional covering up of a floor might occur, then it is important to assess the correct period of time for which the floor heating must be time-limited .
The heating can be limited using a set number between 0 – 20 minutes per hour .
Example: If obstacles could be present that cover up the floor, then the heating might need to be limited by some number of minutes so as to avoid hotspots in the floor .
If you want the thermostat to heat a maximum of 90 % of the time, then the thermostat should be limited by 10 % . Ten percent of one hour is 6 minutes . Enter 6 min . in the EN50559 menu in order to lower the heating by 10 % .

Troubleshooting 3/7

I CAN’T CONNECT TO MY WIRELESS NETWORK

Possible causes

Solution

Insufficient WiFi signal

Try connecting another device, such as your mobile phone, to your wireless network . Stand next to your WiFi Thermostat, and access your phone’s wireless network settings . If the wireless network signal cannot be detected by your phone, or it is very weak, other devices may also have trouble connecting to the network from that area of your home . You may be too far away from your WiFi router, or there may be a problem with it . If you are too far away from your WiFi router, you can purchase a WiFi signal repeater which will improve the range of the WiFi signal in your home for all devices .

You cannot connect to the WiFi router even though there is a good signal

Some WiFi routers limit the number of wireless devices that can connect to the Internet . To test whether this is the problem, shut down one of the other WiFi-enabled devices in your home . Once that device is completely shut down, try once again to connect your WiFi Thermostat to the network . If the WiFi Thermostat connects successfully, consult the documentation for your access to find out if you can increase the number of simultaneous connections to your WiFi network .

Other devices are interfering with the wireless signal

Try turning off other wireless devices (Bluetooth, WiFi, wireless phones/cameras) that may cause interference, then test the WiFi Thermostat’s network connection .

You have entered the correct SSID and network key, but connection cannot be established .

Please check the router manual for additional help on troubleshooting .

< Contents >

Troubleshooting

I CAN’T CONNECT TO MY WIRELESS NETWORK

Possible causes

Solution

Your WiFi router does not match the technical requirements supported by the Thermostat WiFimodule

The WiFi router has to match the technical specifications supported by the Thermostat WiFi-module:
· Wireless standard: 802 .11 b/g/n · Security Mechanisms: WPA-PSK/WPA2-PSK · Encryption: TKIP/AES · Frequency range: 2 .412GHz-2 .484GHz

Please check your router manual to confirm this . Also make sure that no firewalls are blocking the communication from the thermostat to the Internet (port 9513) . New item .

Your WiFi router has insufficient security

With so many home devices now connected to the Internet, we want to make sure that your WiFi Thermostat is connected to a secure network so that hackers cannot gain control of devices in your home . WiFi routers utilize two main types of protective encryption: WEP and WPA . WEP is the original form of encryption and it offers very little security . Hackers can very easily break into your wireless network if your router is set up for WEP encryption . WEP encryption was replaced with WPA encryption in 1999 and WPA2 in 2006 . WPA is a security protocol that makes it much more difficult to break into networks . Your WiFi Thermostat currently supports WEP, WPA and WPA2 encryption . If your router was manufactured after 2003, you should be able to change the setting from WEP to WPA by following the guide in the link: (http://www .tech-faq . com/how-to-change-wep-to-wpa .html) .

If that is not possible, contact your network administrator .
