Hotwire HW-WiFi Smart Wif Thermostat Instruction Manual

Hotwire HW-WiFi Smart Wif Thermostat 

Menu Overview

Introduction

Thank you for buying our touch thermostat. We hope you will enjoy the ease of use offered by the touchscreen and intuitively designed interface. You can program the thermostat any way you want with the options provided under Heating Schedule and User Settings. The thermostat will switch on your heating system at predetermined times each day of the week. You can set individual temperatures for up to six separate periods, called events, for each day of the week. Lowering the temperature when your home is unoccupied will reduce your energy costs without reducing comfort. The thermostat comes with a preset heating schedule suitable for most homes. Unless you change the settings, the thermostat will operate according to this preset heating schedule The thermostat features an adaptive function that automatically changes heating start times to ensure that the required temperature has been reached at the beginning of any specific event. After a few days, the adaptive function will have learned how much earlier the heating must be switched on. The resistive touchscreen only requires a soft tap with your fingertip to register the touch. In this manual, the touch areas on the screen will be referred to as buttons. The WiFi version of the this touch thermostat offers remotely control of your underfloor heating – through the SWATT® (Smart Wifi And Touch Thermostat) app, which can be downloaded from both Google Play and App Store.

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 %.

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 .

I CAN’T CONNECT TO MY WIRELESS NETWORK*
Possible causes	Solution
Your WiFi router does not match the technical requirements supported by the Thermostat WiFi- module	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) . Your WiFi Thermostat can still control your floor heating system without wireless network connection . As the best course of action, OJ Electronics recommends that you upgrade your security settings to properly protect your network from hackers . If that is not possible, contact your network administrator .

I CAN’T CONNECT TO MY WIRELESS NETWORK*
Possible causes	Solution
Maybe your WiFi router requires a restart/reboot	The problem might be with your router (even if your other wireless devices are still connected) . A simple restart of the router will usually resolve such problems . While most routers simply have to be unplugged and then plugged back into their power source to restart them, you should refer to your router’s documentation for specific instructions .
Maybe your WiFi router firmware needs to be updated	Contact the router manufacturer for instructions on how to update the firmware .
Maybe your WiFi Thermostat has to be reset	Reset your WiFi Thermostat . For details on how to do this, place consult the “Factory Reset” section in this manual . Note! This action cannot be undone, and all your personal settings will be lost .
