10. Temperature monitoring & control
The G031 has three attached temperature sensors each with a corresponding relay. They can be used to
control three individual zones via GSM /APP. These industrial standard sensors provide typical
accuracies of ± 0.5°C over the −55°C to +125°C (-67°F to +257°F) temperature range. Its stainless steel
probe head makes it suitable for any wet or harsh environment.

10.1. Setting Temperature Ranges
The G031 is designed primarily for a heating setup but can also be used for cooling. The wiring is
different depending on whether you are using the relay for a heating or cooling function.
The ON temperature must be at least 1°C lower than the OFF temperature.)
HEATING
: For heating connect your equipment to the G031 in the
normal open
configuration as seen in
the table below.
Relay ON
: the lowest heating activation temperature. (When colder than ‘+/-xxx‘, turn on.)
Relay OFF
: the highest heater operating temperature. (If warmer than ‘+/-xxx‘, turn off.)
COOLING
: For cooling, reverse the way the relays are wired. Connect your cooling equipment in the
Normal closed
configuration as seen in the table below.
It is important to understand that relays wired in ‘normal closed’ position will operate in the
opposite way than expected. In this setup off will turn the relay on. This needs to be taken into
account during setup.
