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).
2. Open the junction box.
3. Connect the wires according to the description in
Chapter "Connections". Optional: Connect external wired
sensors.
4. After verifying the connections, switch on the mains voltage.
3. INSTALLATION DISCLAIMER
Installation must be done by a qualified electrician in
accordance with national building codes. Before installation,
disconnect the power to the device from the mains. During
installation of the device, power to the device must be
disconnected AT ALL TIMES!
4. CONNECTIONS
Max tightening torque for terminal screws: 2Nm.
If the cable used has multiple strands, using an end sleeve is
advised. The product allows for wiring of cables with a cross
section of up to 1x2.5mm2.
The screw terminals are located at the back of the device, and
