5. 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 any damage to 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.
