CONGRATULATIONS
You have acquired the latest micro processor controlled
thermostat to reduce your heating bill. It is made to be
very user friendly and easy to use.
General: The HD series digital thermostat is an battery
operated. For HD-310 & HD-410 are possible to save
energy by decreasing the temperature to "Eco" temp for
shorter periods. These periods can be occasional or
repeating during the day.
You just press the , or button and temperature
will temporary decrease from 20 degree to an economical
℃
"Eco" temp of 16 .
Pre-set:
Set Temperature: 20℃
℃
button: 16 temporary for a period of 2 hours
℃
button: 16 temporary for a period of 4 hours
℃
button: 16 temporary for a period of 6 hours
℃
The Set (Comfort) temperature of 20 and the Eco
℃
temperature of 16 as well as Eco periods 2,4,6 hours
can easily be changed to fit your own need.
The HD series is battery operated, and it can therefore
replace any mechanical standards 2 wires thermostat.
Please however note that the maximal resistive load is 5A.
Installation:
Noted that if you connect the thermostat to a 230V system,
please make sure the power is switched off and that only
a person with good electrical knowledge does the installation.

If you have a mechanical thermostat connected with 2
wires, just take away the old thermostat and replace it
with HD series. Connect the 2 wires to the terminals as
the Fig.2 shows, then put the batteries in and close the
thermostat. See below.
If you don't have a previous
thermostat that you wish to
replace you must install a 2
wires cable to the heating
