Rotex Underfloor Heating User Guide

Rotex Underfloor Heating User Guide

Your new Rotex underfloor heating In this guide you will find information and guidelines that will allow you to run your underfloor heating system in the most energy efficient and cost effective way. We hope you enjoy a warm and comfortable home. System overview In your new home, the energy efficient heating is provided by a Daikin Air-to-water heat pump, with warm water running through underfloor heating pipes down stairs, and radiators on the first floor. To enable you to get the most from your heating, it is important that you understand the concept and how it should be controlled. The underfloor heating pipes are laid across the full area of the floor in the rooms, giving a more uniform heat distribution in comparison to radiators. This provides the home with a warm and cosy feel while freeing up wall and floor space, and is considered to provide a high end finish to any home. As the underfloor heating pipes are embedded in a concrete screed below the finished floor surface, the system needs to heat the screed before it can release the heat in to the room. This means that the time taken for the underfloor heating to respond to temperature changes is considerably longer than a radiator system. Additionally, with underfloor heating systems, the choice of floor covering has an impact on the output from the underfloor heating. It is no coincidence that most pictures of homes with underfloor heating show either stone or tile finished floors, as these conduct the most heat into the room. By comparison, high tog carpets with underlays and engineered timber floor coverings act as insulators restricting the flow of heat into the rooms, and should be avoided where possible. Clock module Programmable room thermostat

Your heating system in detail and getting the most from it The best way to operate your heating system is, through time, to establish a comfortable temperature in each of the rooms, and leave the room thermostat at this setting throughout the day. On the room thermostat is a small red light. When this is lit, the thermostat is calling for heat to top up the room temperature. When the light is off, the room is up to temperature, and no further warm water will pass through the underfloor pipes in this room until the temperature falls and the red light is on. Night time temperature set-back In order to enable the room temperatures to be reduced for overnight periods, the clock module which is located as part of the wiring centre adjacent to the underfloor heating manifold can be programmed for a night time set back. This function reduces the temperature on each of the room thermostats by 4 C for the period programmed. Alternatively, the heating can be maintained at the day time temperatures continuously or the night time temperatures continuously. The following pages describe the programming operation of the clock module. Note: For programming purposes, the clock module can be removed from the wiring centre by gently pulling the top and bottom simultaneously to remove the connectors. The clock module has a 30 day battery life, however for normal operation the clock module must be reinserted to the base after programming.

Useful functions on your underfloor heating clock module Setting the time and date If for any reason you require to re-set the clock 1. Press and hold, until the hours start flashing 2. Press to set the desired value 3. Press to confirm and save the value, the minutes will now start flashing 4. Press to set the desired value 5. Press to confirm and save the desired value 6.

If for any reason you require to change the night set back settings 1. On the main screen, Press to change to Memory screen T1 (or press till you reach the programme which requires adjusting) 2. Press and hold, until the hours start flashing, this will adjust the set back start time 3. Press to adjust the hours, press to confirm 4. The minutes will start flashing, press to adjust the minutes and press to confirm 5. You will then move to the set back end time, the hours will start flashing 6. Press to adjust the hours, press to confirm 7. The minutes will start flashing, press to adjust the minutes and press to confirm 8. The screen will change to Screen B (refer to images on previous page), which will allow you to set which days you wish to have this set back programme active 9. The flashing number will be Start day, press to adjust the start day between 1 and 7 (1-Monday, 2-Tuesday, 3-Wednesday, 4-Thursday, 5-Friday, 6-Saturday, 7-Sunday), press to confirm 10. The end day will start flashing, press to adjust between 1 and 7, press to confirm 11. After pressing the clock icon on the display will start flashing, press until both 1 and 2 are shown, press to save 12. Repeat the above steps for the remaining memory locations if necessary More details of the control functions are available from the installation and operating instructions supplied with the system.

Programming set back times on the radiators The upper floor of the house is heated by radiators. The radiators are larger than normal to enable them to operate at a lower and similar temperature to the underfloor heating, while still heating the rooms to the desired temperature. The upper floor is controlled as a separate zone to the ground floor, and the radiators on the first floor will only heat when the Programmable Room Thermostat (PRT) on the first floor requests heat. Most efficient use of the heating system will be to programme a comfort level temperature at the times when the rooms will be used, and programme an energy saving set back temperature approximately 3 C lower for all other times. The temperature in the room where the Programmable Room Thermostat (PRT) is located is governed by the PRT. The temperature in all of the other rooms is controlled by individual Thermostatic Radiator Valves (TRV) which measures the air temperature in the room and will determine whether heating is required, allowing warm water to pass through the radiator, or stop the water passing through if the room is up to temperature. Programmable room thermostats may vary per installation, details on the specific PRT and programming requirements are available in the user guide supplied by the manufacturer.
