Danfoss Heating

External

Sensor

TPOne includes an optional external sensor input.

If tted select the type of external sensor:

None - No external sensor tted

Room Sensor - Remote room sensor tted. This

will take priority over the TPOne internal sensing.

Danfoss part TS2A - sold seperately

Window Sensor - Where a window sensor has

been tted the TPOne will go into standby mode

while the window is open. Window open feature

is activated 60secs after input is made open circuit.

Window open feature is deactivated 30secs after

input is made closed circuit.

Floor Limit Sensor - This allows for a thermostat

limit sensor to be set, typical application is oor

heating. If the temperature sensed by the limit

sensor exceeds the limit setting the output will be

turned o until the temperature has dropped by

2°C. A warning will be shown on the display that

the oor limit temperature has been exceeded.

Room temperature will be controlled by the

TPOne internal sensor.

The temperature set for the limit point sensor will

be determined by the type of oor.

The recommended limits are:

Tiles on chipboard and wooden oors 27°C

Carpet or vinyl on chipboard 35°C

Tiles on concrete oor 40°C

Concrete, screed, etc 45°C

Danfoss Part TS3 - sold seperately

Lockout - Where a Key lockout switch is tted

the TPOne can be forced into the standby mode

remotely. While activated none of the buttons

can be used and the TPOne will only call for heat

if room temperature falls below set frost protect

level. Lockout feature is activated 60secs after

input is made open circuit. Feature is deactivated

30secs after input is made closed circuit
