10.3 Remote Control via IEEE Interface
Address the controller in listener mode and send a ASCII-String following one of the
templates below.
Note: The SP72 controller will ignore new commands or request while a set
command is executed. Wait 100ms after a set command before adressing the
SP72 controller again.
10.4 Set Commands
T(-)xxxx<CR><LF> Set new set temperature
xxxx is the new temperature value in 1/10°C
(for example:T375 means new set temperature
+37.5 °C and T-105 sets a preset of -10.5°C)
t(-)xxxxx<CR><LF> Set new set temperature
xxxx is the new temperature value in 1/100°C
(for example:T3752 means new set temperature
+37.52 °C and T-1052 sets a preset of -10.52°C)
Please note: Only the negative sign is recognized by the SP72. A temperature
above 0°C must not have a "+" in front of the temperature value.
R+xx-yy<CR><LF> Set deviation range for status display "="
and RI-Request answer "0"
+xx = max. positive deviation in 1/10°C
-yy = max. negative deviation in 1/10°C
i.e. R+12-08<CR><LF> sets the range from
(Set temp. + 1.2°C) to (Set temp. - 0.8°C)
Hy<CR><LF> Set Hold-Mode on or off
y = 0 Deactivate Hold-Mode
y = 1 Activate Hold-Mode
See chapter 8.1 for details about Hold-Mode.
