Question: How is the IT700 thermostat connected to the boiler?
Answer: The IT700 thermostat (specifically the IT700TX model) does not connect directly to the boiler. The physical connection is made through the IT700RX receiver (WZ600), which is included in the set. This receiver is installed near the boiler and connected to its control terminals.
Question: What does the wiring look like?
Answer: Two wires come out of the receiver:
- one from the COM (common) terminal,
- one from the NO (normally open) terminal.
These two wires should be connected to the appropriate terminals on the boiler — in the case of the Buderus GB122, these are usually labeled TA (thermostat terminals). When the circuit is closed (i.e., when the thermostat calls for heat), the boiler turns on the heating.
Question: Does the thermostat require a gateway or special controller?
Answer: No — the IT700 system does not require an additional gateway. The receiver communicates wirelessly with the thermostat via Zigbee and connects to the internet via WiFi, allowing you to control the heating through the mobile app.
Question: What protocol does the IT700 use?
Answer: IT700 uses the Salus Premium Lite app and
the wireless link between thermostat and boiler receiver is a Zigbee 1.2
protocol link.
Question: iT700 – Signal strength check
Answer:
Signal strength (quality) is expressed in decibels (db). Compare the value with the table below:
-50db to 0db - very good signal
-75db to -50db - good signal
-85db to -75db - weak signal
-95db to -85db - very weak signal, wireless connection almost impossible
In the Salus Premium Lite app:
1. Tap the Cog icon at the top right corner of the background image.
2. Select the "Scan my home" option
3. Here you can check the signal strength level of the iT700
Note:
While grey it displays a static value, of the signal strength, read when scan was performed.
You can click on it to turn it blue (active), while blue it will display the current active reading of the signal strength.
