iSense 1. Preface 1 Preface 1.1 General The Remeha iSense is a timer thermostat with many enhanced functions. The controller is supplied in a OpenTherm and RF variant: 4 iSense OpenTherm. 4 iSense OpenTherm RF(Wireless). With the iBase RF transmitter. This installation and service manual describes all the functions of the iSense.
2. Location of the installation iSense 2 Location of the installation 2.1 Position of the regulator Controller OpenTherm and controller RF The controller is set to room control by default. The controller can be installed on an inside wall or in a boiler, if the boiler is suitable for this. This means that the inside temperature is used to control the central heating. It is therefore best to locate the controller on an internal wall in the room in which you spend the most time, such as the living room.
2. Location of the installation iSense 2.2 Installation and connection Before you can connect the controller, you must first: 4 Adjust the boiler so that it can be connected to a OpenTherm controller. See the installation and service manual for the boiler. 4 Shut down the boiler. To do this, proceed as follows: 1. Open the housing by pulling the front and the base plate apart. T001046-D 2. Attach the base plate to the wall using the screws and plugs supplied.
iSense 2. Location of the installation 4. (Only controller OpenTherm) Place 3 AA batteries in the controller if necessary. These are not supplied. The batteries ensure that the clock keeps running when the boiler is switched off. The batteries also power the backlights of controllers for boilers that do not have OpenTherm Smart Power. If you have a boiler with Smart Power, then the backlight of the controller also works without batteries. (Only controller RF) Insert 3 AA batteries into the controller.

If the set room temperature is below the value set at Night temp., Then the DHW standby function is switched off by default. ¼ "Controlling the tap water temperature", page 18 4.1.3.
iSense 4.2 4. Setting Operating the controller 4.2.1. Selecting a program You can select one of the following programs via Program in the main display: 4 Clock prog.: The central heating temperature is controlled by the program you have set. 4 Continuous day program: The temperature remains constant at the day temperature you have set. 4 Continuous night program: The temperature remains constant at the night temperature you have set.
iSense 4. Setting 4.2.3. Fireplace mode Once the temperature has reached the desired level in the room where the controller is located, the central heating switches off. This may be inconvenient if you have an open fire. Or if a lot of people are present. Other rooms in the house are also no longer heated in this situation. In order to ensure other rooms are still heated, you can switch on the fireplace mode. You do this via the Program button.
4. Setting iSense 4.3 Changing usage settings 4.3.1. Large information line Small information line Setting the display Set the following via: Menu > Settings > Users > Display 4 Info line small: Select what information should be displayed on the small information line. 4 Info line large: Select what information should be displayed on the large information line. 4 Light time-out: Set how many seconds the backlight should remain on after the last button is touched. T001037-04-C 4.3.2.
iSense 4. Setting Some settings can only be changed in the mode Extended mode. The settings you create remain enabled in the modes Basic mode and Normal mode. 4.3.5. Resetting factory settings You can reset all settings, including the clock program, to the works setting via: Menu > Settings > Users > Reset 4.3.6. Calibration You can adjust the measuring value from the inside and outside sensors via: Menu > Settings > Users > Calibration.
4. Setting iSense Other: You can set the start and end of summer time yourself by indicating the month and the week. The time will change on the Sunday. Manual: The controller does not switch between summer and winter time. The time must be changed manually. 4.3.10. Comfort correction It feels more comfortable when the radiators in the home are hot (Between 50°C and 90°C).The perceived temperature is higher than the real temperature due to the radiant heat.
iSense 4. Setting 4 Both functions are active simultaneously. 4 The T icon is shown in the display when DHW standby is switched off. Time Desired room temperature 07:00 20℃ 09:00 15℃ T 11:00 13:00 15:00 17:00 19:00 21℃ 21:00 23:00 15℃ T 00:00 DHW standby The combi-boiler pre-heats periodically in order to be able to meet the demand for hot tap water quickly.
iSense 4. Setting The maximum temperature that can be set depends on the boiler settings. When setting a clock program, start this an hour before you require the first hot water. This gives the boiler sufficient time to heat up. 4.3.13. Central heating settings You can set a number of specific central heating settings via: Menu > Settings > System > CH system: 4 Pump control: When this option is switched on, the pump switches off when there is no demand for hot water.
4. Setting iSense 4.3.14. Frost protection - System You can use the frost protection system option to protect radiators in frost-sensitive rooms against freezing. For example: The temperature in the home at night does not drop below 19℃, which means the pump does not come on. The radiator in the annexe, which gets colder, runs the risk of freezing. The frost protection system option is automatically switched on if you have an outside sensor.
5. Selecting the control strategy iSense 5 Selecting the control strategy 5.1 Six control strategies The controller can be used as a weather compensator or as a room thermostat (Room control). Six control strategies are available for this. 1 RTC: (Modulating control) Room control The control measures the room temperature in the reference room (the room where the thermostat is located). The required flow temperature based on an intelligent control system is now calculated.
iSense 5. Selecting the control strategy Adjustments are not needed in the room where the controller is located. Any radiator valves present in the reference room must be fully opened. 4 OTC + C-RT: Weather-compensated with comfort function The basis of this control strategy is the same as weathercompensated control. The heating curve must therefore be correctly entered. The heating curve is also shifted on the basis of a room temperature that is calculated (therefore not measured).
iSense 5.3 5. Selecting the control strategy Specific settings for weather-compensated control If you have opted for a weather-compensated control strategy, a number of extra settings are available via: Menu > Settings > System > OTC settings > Heating curve Increased room temperature during the day Desired room temperature of 20ºC during the day Desired room temperature of 15ºC during the night 4 Base outside: Outside temperature base point.
5. Selecting the control strategy 5.4 iSense Heating curve - For example The settings for the heating curve are highly dependent on the design of the central heating system and the home. This means that no clear advice can be given on this matter. Use the tables below as a basic setting if you do not know the design information. The heating curve can be optimised during use. The heating curve also shifts upwards or downwards when the temperature is increased or decreased.
6. Installer settings iSense 6 Installer settings 6.1 Telephone number for service messages and failure signals You can enter a telephone number to be shown if the boiler displays a service message or failure signal. Select: Menu > Settings > Installer > Phone number > Service or Repair No telephone number is shown with the message if no telephone number is entered. 6.2 Service messages on or off You can set whether service messages from the boiler can be shown on the controller.
