6. Thermostat Functions

NSB (Night SetBack) Function

NSB Mode depends on the NSB wired connection. 

 

0V =   NSB OFF
24V=     NSB ON

The NSB signal is activated every 1 second. When the signal is received the 
setpoint temperature will be set at 

±

2°C or 

±

4°C.

Heating and Cooling Selection

The Heating/Cooling function is determined by the CO terminal connection.

CO 0V=    Heat mode 
CO 24V=    Cool mode

Cooling Blocked function

Cooling Enabled:
Set the jumper on ON                   . The thermostat will run in normal cooling mode. 
That means that it will open/close the actuators when necessary. The LED will be 
BLUE when the cooling function is running.

Cooling Disabled:
Set the jumper on OFF                .  The actuator will be closed and the LED will 
be off.

Heat cut off at high/low temperature:

When room temperature is over 36°C or under 4°C, all heating/cooling outputs 
will be turned off.

Short cycle protection:

When Cooling Mode is enabled the minimum interval between Relay ON/OFF 
is 3 minutes.

Valve Protection:

Set the jumper on ON to disable the function or on OFF to enable it. Turn on the 
valve for 5 minutes every week to prevent the valve any damages on the valve.

Sensor Malfunction:

If the temperature sensor or temperature sensor compensation is open the LED 
will flash BLUE/RED alternatively.

If CO terminal is connected and the Heating Mode is ON, the PWM function 
will be activated.

If CO terminal is disconnected and the Cooling Mode is ON the ON/OFF control 
output will be activated.

Note: You can wire the thermostat 
directly to the KL06 24V Wiring 
Center (purchased separately).

Wall mounting

For wall mounting, mark the correct 

possition on the wall and mount the 

rear case to the wall.

Install the HTR24 dial room thermostat at roughly 1.5m above floor 
level. It should be mounted in a location where the thermostat is 
easily accessible and away from direct sunlight. You can mount 
the thermostat directly on the wall or you can install it on top of a 
wall-box.

The jumpers from 1 to 5 are representing the number of actuators that you can connect 
to the thermostat.

After the actuators are mounted please move the jumper on the correct number (the 
same as the number of actuators).

Depending on the amount of actuator used, please change the jumper position 
accordingly to compensate the power consumption.
