Temperature calibration：The thermostat may indicate a temperature different
from the real one due to its location in the house. After choosing the place of
functioning thermostat, it is useful to calibrate it. Use a precision thermometer near
the thermostat that you keep a minimum of 50 minutes. Press and hold SET and
MODE until the temperature remains on the display only. Enter the thermometer
indicated value standard by turning the wheel on the side of thermostat and press the
SET.
Warning: the thermostat does not show correct temperature value and does not allow
calibration in less than 50 minutes after the electrical supply! The temperature is
correct and the device can be calibrated only after the symbol "C grade" goes from
small c to big C .

On RF communication is normal
Radio communication inside the house building structure can be influenced by many
factors and external variable and impossible to predict. Generally concrete structure of the
metallic support of plasterboard panels or large metal objects are an obstacle to the
airwaves. Placing the thermostat in the control room and the receiver near the boiler must
be carried out so that radio communication to be more stable.

the selected set point temperature.
④ Program mode: When set to Program, Cloudwarm runs the program preset via
App on mobile devices or web use.

① There are 4 wires from receivers: wires from receiver labeled “OT” to be
connected with thermostat port of Open Therm protocol supported boiler; Wires labeled
“ON/OFF” to be connected with thermostat port of Non-Open Therm supported boiler. Use
screw driver to connect the wires respectively.
② Use black magnetic pad or white double side sticker in the accessory bag to stick
receiver to a proper place depending on the wall surface quality, or use the screws to fix
receiver onto wall.

*The manufacturer reserves the right to change specification without prior notice.
*OT is short for Open Therm, a point-to-point communication system and connects boilers
with room controllers. Open Therm assumes that the room controller is calculating a
heating demand signal in the form of a water temperature Control Set point based on
room temperature error which it needs to transmit to the boiler so that it can control the
output of the boiler. The boiler in turn can transmit fault and system information to the
room controller for display or diagnostics. ( Selected from “Open Therm Protocol
Specification v2.1”)
