APPLICATIONS

• Applied for temperature mode control in ventilation, heating and air conditioning systems.
• Can be applied for control of fans and fancoil valves, air heating units with 230 V three speed fans.
• Automatic heating or cooling rate control.

DESIGN AND CONTROL

• The temperature sensor is built into the plastic control panel casing.
•  A digital light-up LCD display and control knobs are located at the control face panel.
• The display shows the current and set indoor air temperature, selected mode for cooling, heating or automatic mode as well as set motor speed.
• The rotation speed can be adjusted manually by means of control knob rotation.
• Provision is made for automatic control of rotation speed (quick/medium/low) depending on the indoor temperature.
  • The light-up display enables the regulator operation in bad light conditions.
  • Temperature maintaining within up to 1^оС.
  • Saving settings at no power supply.
  • RTSD-1-400 model is equipped with remote control panel.
  • Night duty operation (refer to operation mode for night duty below).

MOUNTING

• Control panel is designed for indoor surface mounting.
• The recommended installation height is 1.5 m.
• Do not install the control panel close to windows, doors, heating or cooling devices.
• The controller is designed for indoor mounting into special flush mounting junction box MKV-1 (under separate order).

NIGHT DUTY OPERATION PECULIARITIES

• Operation of the temperature regulator in the heating mode: in 30 minutes after switching to the night duty the indoor temperature goes automatically down by 1^оС and in 1 hour the temperature goes down by 1^оС more. One hour later the temperature goes down by 1^оС more and will be kept at this level within 8 hours. After switching the timer off the temperature will be reset to the reference set level automatically.
• Operation of the temperature regulator in cooling mode: in 30 minutes after switching to the night duty the indoor temperature goes automatically up by 1^оС and in 1 hour the temperature goes up by 1^оС more and will be kept at that level up to 8 hours. After switching the timer off the temperature will be reset to the reference level automatically.
