Unauthorized modifications are prohibited. The product must not be used in relation with any equipment that in case of a failure may threaten humans, animals or assets. Ensure all power is disconnected before installing. Do not connect to live/operating equipment. Only authorized specialists may carry out installation. All applicable legal or institutional installation regulations must be complied during installation. The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed. The measuring result is influenced by the thermal characteristics of the wall. A solid concrete wall responds to thermal fluctuations within a room more slowly than a light-weight structure wall. A room sensor always detects a mixture of air and wall temperature. This means that the radiant heat of the wall, which is important for comfort, is also included in the measurement result. Temperature sensors with electronic components always have a dissipative power which affects the temperature measurement of the ambient air. The dissipation in active temperature sensors shows a linear increase with rising operating voltage. The dissipative power should be taken into account when measuring temperature. Belimo room sensors have adaptive temperature compensation for the entire supply voltage range. This ensures that the ambient temperature is detected with the highest accuracy at all times.22RT..-5900D • en-us • 2022-09-19 • Subject to change3 / 6 Refrain from touching the sensitive humidity sensor element. Touching the sensitive surface will void warranty. When exposed to harsh environmental conditions such as high ambient temperature and/or high levels of humidity, or presence of aggressive gases (i.e. chlorine, ozone, ammonia), the sensor element may be affected and readings may be outside the specified accuracy. Replacement of deteriorated humidity sensors due to harsh environmental conditions is not covered by the general warranty. The sensor shows best performance when operated within the recommended normal temperature range of 0...50°C [32...122°F] and a humidity range of 20...80% RH. Long-term exposure to conditions outside the normal range, especially at high humidity, may temporarily offset the humidity signal (e.g. 3% RH after 60 h kept at >80% RH). After returning into the normal temperature and humidity ranges, the sensor will slowly come back to calibration state by itself. All CO₂ sensors are subject to drift caused by the aging process of the components, resulting in regular re-calibration or replacement of units. However, the dual channel technology integrates automatic self-calibration technology vs. common used ABC-Logic sensors. Dual channel self- calibration technology is ideally suited for applications operating 24/7 hours such as those in hosiptals or other commerical applications. Manual calibration is not required. The operating display is an ePaper display that reflects light like normal paper. It is therefore a non-illuminated display with an integrated touch control panel. The representation on the display can be designed freely, depending on the requirements. Function blocks can be switched on or off by using the Belimo Assistant App. By default, all actual values and temperature setpoint adjustments are visible on the display. Colours: green, yellow and red. LED can be parametrised and deactivated via Belimo Assistant App. Symbol is displayed if an internal error occurred or if warning is transmitted by the controller via the connected bus (external error). Symbol is displayed if the HVAC system is either completely off or in building protection mode. If this symbol is activated, the rest of the display is blank. The operating elements on the ePaper display are touch fields that can be operated with the finger. The touch fields are only active if the corresponding element is also displayed. 1 2 3 4 5 6 7 8 9 10 1122RT..-5900D • en-us • 2022-09-19 • Subject to change4 / 6 Absolute setpoint:10...40.0°C or 50...104.0°F Relative setpoint:-5...5°C / °F Adjustable and restrictable via Belimo Assistant App Symbol can be displayed if the HVAC system is either completely off or in building protection mode.
