Room thermostat with 24-hour time switch and large LCD RDJ100 Programmable, for heating systems ● ● ● ● ● ● ● A6V10954415_en--_f 2020-10-29 2-position or PID control to switch on/off heating systems Operating modes: Automatic, Comfort, Energy saving, and Frost protection 24-hour time switch Service interval reminder Large LCD display Minimum and maximum setpoint limitation Battery powered: 2 x alkaline type AA batteries, 1.
Use The device is used to control the room temperature in heating systems. Typical applications: ● Homes ● Residential buildings ● Schools ● Offices The device is used together with the following equipment: ● Thermal valves or zone valves ● Combi boilers ● Gas or oil burners ● Pumps Functions Temperature control RDJ100 offers both 2-position and PID intelligent learning temperature control, configurable via parameter P01 (control behaviour).
Control behaviour (P01) The factory setting for control is “PID slow”, ideal for most heating systems.
Operating modes The device has the following modes: Automatic, Comfort, Energy saving and Frost protection. Move the operating mode slider to the respective position to select another operating mode. Automatic mode Automatic mode is active when symbol is displayed. The device operates as the selected 24-hour time program. Comfort mode Comfort mode is active when symbol is displayed.
Parameter setting mode 1. Press RESET on the rear for 5 seconds until “P01” appears. Note: Pressing the button longer than 10 seconds resets the thermostat. 2. Press advance button, the parameter value on the second line flashes and is ready for adjustment. 3. Adjust the parameter using setting knob. 4. Press advance button once to confirm the setting. 5. Rotate the setting knob clockwise to next parameter and repeat steps 2 to 4. 6.
If service interval function is enabled and operating mode selector is set to Standby mode or set to other mode from Standby mode, the screen will display the remaining days until next service due. The service interval reminder can be enabled and reset by a service professional.

Instructions for the replacement of alkaline batteries WARNING Explosion due to fire or short-circuit, even with discharged batteries Risk of injury due to flying parts ● Prevent the batteries from coming into contact with water. ● Do not recharge batteries. ● Do not damage or disassemble batteries. ● Do not heat batteries over 85°C. WARNING Leakage of electrolyte Severe burns ● Handle damaged batteries only wearing suitable protective gloves.
● ● ● ● Do not mount the devices in recesses, shelves, behind curtains or doors, or above or near heat sources. Avoid direct solar radiation and drafts. Seal the conduit box or the installation tube if any, as air currents can affect sensor readings. Adhere to allowed ambient conditions. Installation WARNING No internal line protection for supply lines to external consumers.
WARNING No internal fuse External preliminary protection with max. C 10 A circuit breaker in the supply line required under all circumstances.
