Product info
1. INTRODUCTION
Heatit Pro is an electronic thermostat designed for electrical
heating, waterbased heating and cooling systems. The
thermostat has a user-friendly interface that can be controlled
from the buttons on the front of the thermostat.
Heatit Pro has 2 modes; Heat and Cool.
The thermostat fits in standard European junction boxes and
may be used with most System 55 frames. It has a sturdy metal
frame for secure fastening on the junction box. The thermostat
has one built-in room temperature sensor. Two additional
external temperature sensors may also be connected.
Heatit Pro has the option of a weekly program and open
window detection.
The product has implemented ZeroX technology. This
technology makes sure the relay switches at 0V when turning
on and off. With this technology the thermostat will have a
much longer lifetime.
Heatit Pro has active power metering, which allows the user to
see the real time power consumption.
The thermostat can withstand a load of max 16A/3600W at
230VAC. We recommend a contactor for loads above 13A.
2. QUICK START
1. Switch off the mains voltage (disable the fuse).
