Cooling blocking function.
Cooling on: Set the jumper to ON
in cooling mode if 230V AC will appear at the CO terminal. The
LED lights up blue when the thermostat sends a signal for cooling.

Night setback – NSB function
The NSB (Night Set Back) function enables automatic reduction of the
temperature setpoint on the daily thermostats, via the programmable
thermostat connected to the wiring centre. The temperature change takes
place between day and night temperatures. When the night mode is activated,
the programmable thermostat sends a voltage signal to the daily thermostats
via the wiring centre. Then, the HTR230(20) thermostat automatically reduces
the temperature setpoint on the knob by 2° or 4° (as set on the SETBACK
jumper). In heating mode, the temperature is lowered when 230 V AC voltage
appears at the NSB input.
Make sure that the thermostat is not connected to the 230V AC. Remove the
knob by pulling it towards you, and then open the front cover as shown in the
figure above.
Note:For the proper NSB function work, an appropriate cable
connection is required. TThe connection description is on the previous
page.

The functions of the HTR230(20) thermostat can be switched on and off by
jumpers. Please refer to the table below:
Valve Protection
Set the jumper to ON –
to enable or OFF –
to disable the
function. This function activates the thermostatic valve for 5 minutes once a
week to prevent valve against stuck (caused by limescale).

The thermostat gives a possibility to choose the mode of controlling the room
temperature by PWM algorithm (default) or hysteresis +/-0.5°C. The PWM
algorithm is designed for underfloor heating (for heating systems with high
inertia) – to precisely maintain the room temperature.

Technical informations
Jumpers 1 to 5 correspond to the number of actuators connected. This jumper
is factory set to position 1, which means that the thermostat controls one
actuator. Depending on the number of actuators used, the jumper position
must be changed to ensure optimal operation of the temperature thermostat.
