Set Mode page
The Set Mode function is used to configure the heating and cooling mode on the RFTC-3 device. The user can easily switch between different heating and cooling modes based on the desired usage.
Mode Setup
The user can select the desired control mode based on specific needs and preferences.
Presence Mode: Ideal for dynamic environments where room occupancy frequently changes.
Weekly Mode: Enables precise temperature control based on a weekly schedule, regardless of current occupancy.
Presence Mode
In Presence Mode, regulation is based on the presence of people in the room. When someone is present, the RFTC device switches to Comfort mode, ensuring a pleasant temperature. If the room is unoccupied, the device automatically switches to Standby mode, helping to conserve energy. 
Weekly Mode
In Weekly Mode, regulation is carried out according to a preset weekly schedule. This mode does not consider the presence of people in the room but instead relies on a time-based plan set by the user. The device follows this schedule regardless of room occupancy.
Regulation
The regulation mode setting determines the default mode for heating or cooling based on the user's needs.
Heating: This mode sets the device to heating as the default, meaning it will regulate temperature to maintain the desired warmth in the room.
Cooling: This mode sets the device to cooling as the default, meaning it will regulate temperature to maintain the desired coolness in the room.
Window Function
Mode Change to Standby: When a window is opened, the regulation mode automatically switches to Standby. This minimizes the loss of heat or cool air from the room, saving energy.
Turn Off Regulation: When a window is opened, regulation is completely turned off. Heating/cooling or the fan stops entirely until the window is closed again.
Mode Select
The Mode Select function allows users to set desired temperatures for different operation modes. The available modes include:
Comfort: The device provides maximum comfort for users, maintaining a pleasant temperature and other conditions.
Standby: In this mode, energy consumption is minimized. The device is on standby and maintains a predefined temperature.
Economy: This mode helps save energy by reducing device consumption to a minimum without significantly compromising user comfort.
Building Protection: Designed to protect the building from extreme conditions (e.g., frost), preventing damage to the system or structure.
Regulation Delay Time
This value sets the minimum time interval that must elapse after the last output change before another change can occur. It helps prevent too frequent switching (e.g., due to fluctuating input values), ensuring more stable regulation. If conditions change during this period, the output relay will not react until the delay has passed.
Relay Change Time
This value sets the minimum time gap between turning off one output relay and turning on another. It is used, for example, when controlling multi-speed fans to avoid simultaneous activation of multiple relays or switching too quickly without sufficient delay. This protects the controlled device and extends its service life.
Fan Setup
Controller
Relay – The relay controls the designated relays for different fan speeds:
Low – low speed
Medium – medium speed
High – high speed This setting also applies to external RF relays added in the Periphery section.
0–10 V Regulation allows the fan to be controlled using PID regulation, which ensures smooth and precise speed adjustment based on current conditions.
This option enables quick fan regulation in ON/OFF mode using a 0–10 V signal.
Relay Regulation
Hysteresis Hysteresis works in fan regulation using only one hysteresis value, which is set in the Temperature Settings section. This value determines the range within which the fan turns on or off depending on the current temperature.
Set Value This works with threshold temperature values that are configured in the High, Medium, Low fan set value fields. The user can define different hysteresis values for various temperature levels, allowing finer control over fan switching behavior.
Percentage When the system detects a temperature deviation, it calculates corresponding values based on preset fan percentages. For example:
If distribution is 70% medium, 30% low up, and 10% low up in degrees,
Then:
If the difference is greater than 30%, the valve fully opens
If the difference is between 10% and 30%, it opens to 30%
If it’s less than 10% and within the hysteresis range, the valve stays open until the opposite threshold is reached Valve relays only activate to open the valve and never operate continuously. When the system is off, it will resume once the hysteresis boundary is crossed.
Fan Value Settings (High, Medium, Low)
Here, the user sets threshold temperatures at which the fan activates at the appropriate level.
If the temperature exceeds the set value for High, Medium, or Low, the fan will turn on at the corresponding speed.
Valve Setup
Controller – Relay – Permanent Permanently On Relay This setting allows heating/cooling to be controlled via a relay that remains constantly on while active. The relay switches off only when leaving the active state (e.g., out of range or mode). Relay Hysteresis This sets the temperature range (or other controlled variable) in which the relay state does not change, preventing frequent toggling. Example:
Target temperature: 22 °C
Hysteresis: 1 °C
The relay switches on below 21.5 °C and off above 22.5 °C. 2-Point Relay Used for controlling 2-way valves. The relay switches between two positions, managing flow of hot/cold medium. 3-Point Relay Used for controlling 3-way valves. The relay manages the flow via three positions for more complex regulation of heating/cooling medium. 0–10V Regulation Allows valve control via a 0–10V signal for smooth modulation of medium flow based on current needs.
Opening/Closing Time
This function defines the time a 2-way or 3-way valve takes to fully open or close.
Opening/Closing Duration: Specifies the time required to completely actuate the valve after it’s switched on or off.
Temperature Settings
Hysteresis
Hysteresis is the difference between the value at which an action is triggered (e.g., turning the heating on) and the value at which the action is turned off (e.g., turning the heating off). The user can set the hysteresis value according to their preferences to stabilize temperature regulation.
Offset
Offset allows the user to correct deviations in temperature measurement. If the temperature displayed on the device differs from the actual room temperature, this deviation can be corrected using the offset value.
Manual Minimum and Maximum
This function allows the user to define the minimum and maximum temperature limits that can be set directly on the RFTC device display. It prevents users from selecting a temperature outside the range defined by the administrator or device configuration.
Temperature Sensor
The user can select from different temperature sensors or a combination of them for room temperature monitoring. Available options:
Internal sensor
External wired sensor
External RF sensor
Combination of sensors When multiple sensors are selected, the device calculates the average temperature value.
Mode Temperature Settings
In this section, the default temperatures for specific operation modes can be defined, such as:
Comfort: Default temperature for the Comfort mode, ensuring maximum user comfort.
Standby: Maintains temperature in energy-saving standby mode.
Economy: Used in Economy mode to help conserve energy.
Building Protection: Applied in Building Protection mode to prevent damage to the building from extreme conditions.
