Comfortheat MWD5 HYDRONIC Programmable Thermostat Operating Manual

Comfortheat MWD5 HYDRONIC Programmable Thermostat

A Comfort Heat heating system has been installed on your floor. Floor heating warms from the ground up providing an unparalleled feeling of comfort. This heating system is controlled by an electronic thermostat and floor sensor for optimum temperature control.

MWD5 DETAILS
The MWD5 WiFi touchscreen thermostat has a built-in programmable time clock to automatically turn the heating system UP and DOWN at selected times. During the DOWN periods, the floor does not turn OFF but programs the floor temperature to a setback temperature. The floor is heating when the LCD display temperature turns red. Thermostats can be vertically or horizontally flush mounted and have a 2-pole isolator with a 16A output relay. PRIOR TO

TURNING ON

Concrete slabs and screeds must be fully cured before turning the floor heating system on. Wait at least 3 weeks and when turning it on for the first time, increase the floor temperature gradually over 2-3 days. Under timber and radiator systems can be turned on once the installation is complete.

RUNNING GUIDELINES

Gas systems are ideal for on-demand heat. Gas boilers are efficient any time of day, quiet to run, and billed at a flat rate. Heat Pump systems are at the forefront of hydronic heating and can be highly cost-efficient to run. Heat pumps require a range of considerations when running, for example, the location, appropriate time of use, and efficient times to run. In-Slab installations are typically large and have excellent thermal mass. Initially, the slab may take a few days to warm and then only requires to be topped up to create an all-day warmth. Allow 2-4 hours for the slab to top up.

In-Screed installations typically heat up in around 2-3 hrs depending on the screed thickness. Screeds will retain the heat for a few hours and by keeping doors closed and windows shut, retain the warmth for an efficient and comfortable room temperature. Programme the in-screed heating to run when at home, based on your lifestyle. Under-Timber installations warm the small air space below the timber allowing this warmth to gently rise into the room. Under timber, heating has a maximum temperature limit and may require supplemental heating to warm the room. Radiator systems are ideal for on-demand heat. One master thermostat and radiator typically control the whole system based on the air temperature. Each additional radiator is then fitted with a tempering valve that is manually adjusted to regulate each room. Radiators will warm a room in around 1-2 hours, program the radiator heating to run when at home, based on your lifestyle.

Adaptive Function – Turn OFF
This feature enables the room to reach the set temperature at a set time. The adaptive function calculates the heat-up time and will turn the system on or off to achieve the set temperature at the set time. Eg. the Thermostat calculates it must turn on at 5.00 am to be at 25°C at 6 am, as opposed to turning on at 6 am to heat to 25 °C.

Open Window – Turn OFF
The thermostat can detect an open window by registering a rapid drop in room temperature. With the function enabled, the thermostat shuts off the floor heating for 30 minutes.

Temp Scale – Adjust to 5°C
This option allows you to set the minimum and maximum temperature to which the thermostat can be set.

TROUBLESHOOTING

For a successful remote connection you must have the following;

1. Logged into your SWATT app account on your device.
2. Each thermostat is connected to your WiFi network. If no WiFi connection is available, try turning your router off/on. Thermostats may be too far away from the router to join the WiFi network.
3. WiFi network connected to the internet. In some cases, you may be successfully connected to your WiFi network but your internet is down. Check the internet connection with another device.
4. Successful server connection [automatic] If your server is not connecting it is either your WiFi, internet, or the SWATT server is down. Any questions please feel free to contact Comfort Heat Australia at 02 9979 8600
