Setpoints
This section outlines the registers for setpoints configuration.
SETPOINT_VALUE (41501)
The register stores an actual setpoint value multiplied by 10. After device restart, the value is read from the DEFAULT_SETPOINT_VALUE register and set as the actual setpoint value. The default value is 210.
EFFECTIVE_SETPOINT (31502)
The register represents a sum of the actual setpoint value and offset setpoint value. This value is a final setpoint value.
DEFAULT_SETPOINT (41503)
The register contains a default setpoint value. The default setpoint is set as a setpoint value after the room panel restart or power supply reconnection (the value of the DEFAULT_VALUE register is written down to the SETPOINT_VALUE register). The register contains value multiplied by 10. The default value is 210.
OFFSET_SETPOINT (41504)
The register contains a value which allows for setting a correction for the setpoint value. The offset value can be positive or negative. The offset setpoint value is added to the setpoint value and the result value is entered to the EFFECTIVE_SETPOINT register. The register contains value multiplied by 10. The default value is 0.
SETPOINT_LOW_LIMIT (41505)
The register contains a minimum setpoint value, which can be set by the user, multiplied by 10. The default value is 180 (18oC).
SETPOINT_HIGH_LIMIT (41506)
The register contains a maximum setpoint value, which can be set by the user, multiplied by 10. The default value is 240 (24oC).
OFFSET_RANGE (41507)
The register contains a value, which limits the offset setpoint value change, multiplied by 10. The value creates a range from – OffsetRange to + OffsetRange of possible offset values, which can be set by the user. The default value is 30 (3oC).
For example:
Offset range value is 20. It means that the user can change the offset setpoint value from -2oC to +2oC.
SETPOINT_STEP (41508)
The register contains a setpoint step value multiplied by 10. If the setpoint is changed by arrow buttons locally from the room panel, pressing of the arrow button causes a setpoint change with the step value stored in this register. The setpoint can be changed in the range determined by setpoint limits stored in the SETPINT_LOW_LIMIT and SETPOINT_HIGH_LIMIT registers.
The setpoint step is also automatically adjusted to the setpoint display precision. If the register SETPOINT_CONFIGURATION bit 4 is true, the setpoint value is displayed with one decimal place. In that case the setpoint step is also adjusted to one decimal place.
For example:
The SETPOINT_CONFIGURATION register bit 4 is true, and the SETPOINT_STEP value equals 5. The actual setpoint step will be automatically adjusted to one decimal place, so the SETPOINT_STEP value will be scaled to 0.5.
The function is active only if the SETPOINT_CONFIGURATION bit 4 is true. Otherwise, the setpoint value is displayed as an integer value and the SETPOINT_STEP register adjustment is unnecessary. The default value is 10 (1oC).
OFFSET_NAME (41509)
The 32-bit register contains up to 4 characters (ASCII code), which can be displayed as a text (name) on the 14-segment display block together with the OFFSET_VALUE register (displayed on the 8-segment display block). In case if a particular character value is 0 (NULL), the character is not displayed. Lower case characters are automatically changed into upper case characters. The default value is 1179864902, which corresponds to the name “OFFS”.
SETPOINT_NAME (41511)
The 32-bit register contains up to 4 characters (ASCII code), which can be displayed as a text (name) on the 14-segment display block together with the SETPOINT_VALUE register (displayed on 8-segment display block). In case if a particular character value is 0 (NULL), the character is not displayed. Lower case characters are automatically changed into upper case characters. The default value is 1414550341 which corresponds to the name “SETP”.
