9 TEMPERATURE REGULATOR
The internal temperature regulator will operate to keep the ambient temperature near the
setpoint when regulation is on. The system can work in cool or heat mode.
Operating in heat mode an antifrost protection will automatically turn on regulation out [1] until
the measured temperature is above the safety limit.
Regulation control can be made by means of simple calls or SMS from authorized users.
9.1 Edit Temperature regulator
Specific information about parameters related to temperature regulator are stored at index 289,
group 6 and can be written and/or modified by means of GsmSuite programming software.
Such information can be stored or modified also by any supervisor issuing an SMS:
+6,289,,TEMP,SetT,AfrostT,MODE,UNREG,UNIT
9.1.1 SetT
Comfort setpoint temperature in the range 2÷37°C (36÷99°F), can be set also by means of
remote SMS command Setpoint or console command AT#Setpoint.
Choosing SetT=0 temperature regulator will be disabled and main regulation output will be
controlled on/off. Default setting is 0 (disabled).
9.1.2 AfrostT
Antifrost temperature in the range 2÷37°C (36÷99°F). Operative in heat mode only.
Regulation output will be set ON anyway when ambient temperature falls below specified
temperature. Choosing AfrosT=0 the antifrost feature will be disabled even in heat mode.
Default setting is 5 (5°C).
9.1.3 MODE
The regulation operating mode.
0 = cool mode, summer
1 = heat mode, winter (optional antifrost protection could be enabled)
9.1.4 UNREG
Time to reach setpoint from regulation activation in the range 1÷12 hours.
When the ambient temperature doesn’t reach te setpoint within specified time, a regulation
malfunction alarm will occur. This option is useful to detect problem to heating/cooling systems
without having to wire electrical signals.
Default setting = 4 hours.
9.1.5 UNIT
It’s the unit that will be shown after measured value. Up to 40 characters available.
When first character is F or f, all temperature will be shown and considered in Fahrenheit
degrees. Any other character will turn the unit in default Celsius degrees.
9.1.6 Example
+6,289,,TEMP,20,5,1,4,Celsius
Set comfort temperature to 20, antifrost temperature to 5, heat mode, 4 hours reaction time and
temperature shown and considered in Celsius degrees.
9.1.7 Confirmation
Once Phonebook edit has been successfully done, device will send back an SMS specifying
assigned index, name and 7 markers to specify which fields are defined (
*
