Installation & programming manual
WebHeat Control P30
The on-wall thermostat P30 is designed to control heating systems, specifically the WebHeat self regulating
heating cables. The controller switches on the heating sections when the set temperature is below target
(which is measured by a separate temperature sensor). The extra alarm output can signal temperatures below
a pre-set value.
Input:
two temperature sensors: NTC 5k by 25°C
bistate input (normally opened or normally
closed)
Measuring range:
-50...+150°C
Measuring accuracy:
±0,5%
Power supply:
230V~ ±15% or 12V=/~, max 3VA
Display:
LED, 4 digits, 11mm height with graphic icons
Display & setting
resolution:
0,1°C in whole range
Protection class
IP20 / IP65 in supplied housing
Control form:
ON-OFF with hysteresis
Output relay 1:
20 A, 4500 Watt
Output relay 2
(alarm):
8 A, 1500 Watt
Operating
conditions:
-5...60°C; 0...85%RH (non-condensing)
Storage conditions:
-40...85°C; 0...85%RH (non-condensing)
Before you install this controller, make sure to check the current settings and re-program if necessary.
Specifically check function F29, Cooling/Heating, which should be set on HEATING for a correct use. This
controller may only be installed and connected by a nationally certified electrician.
This WebHeat Control P30 has many extra functions that are not necessary for usage in heating cable
applications. Go to our website www.webheat.eu to download the complete installation manual with settings
for other applications, such as cooling, boiler and/or solar applications.

buttons, enter the password and confirm with SET key.
3. Using UP or DOWN key to choose the parameter you want to change and enter
with SET key.
4. Using UP or DOWN button to set the desired parameter value.
5. Using SET key to confirm the new parameter value and return to the parameter
list.
6. Finish programming pressing M button or enter the END command and press
SET key or wait 30 sec without pressing any button.
Remarks:
-Press M button to cancel the parameter setting.
-Hold UP or DOWN button for at least 1 sec to improve quick increasing and
decreasing of setting values.

Connection:
This controller may only be installed and
connected by a national certified electrician.
The sensor should be connected to
terminal 1 and 2.
Heater cable should be connected to
terminal 11, 12 and 15. In case the load
is smaller than 1500 Watt, you can use
either terminal 11 OR 12. When load is
higher than 1500 Watt use BOTH
terminals 11 and 12.
Extra bridge cable should be connected
between terminal 14 and 16.
The earth of the heating cable and the
earth of the power supply should be
connected beside the thermostat to
the ground terminal.
