9.5 Settings for heating
Heating1
The device has two heating circuits (H1 and H2) whereby each heating circuit can control
either a relay (two-point) or a 0 - 10 V output (linear). “ H1 ” is generally the stall heating and
“ H2 ” can be used for an additional heater (aisle, supply air) or for a  oor heating (piglet
nest).
The state of the heating is additionally displayed here for informational purposes:
•
Display in two-position controllers (factory setting mode 1 in the installation menu)
– OFF = Heating is currently switchedoff
– ON = Heating is currently switchedon
•
Display during linear heating control ( Installation - Heating-Mode 2)
– 0 - 100 % 0 - 10 V or 10 - 0 V
The display changes if both heating circuits are operated: “ Heating 1 ” / “ Heating 2 ”
The mode: Tow-point / 0 - 10 V (linear) or Heating inactive andthe sensor input usedas
an actual value is de  nedin the menu Installation - “ Heating 1 ” or “ Heating 2 ” . The
possible settings depend on the speci  edmode. The assignment on which relay or
analogue output the heating circuit acts is set under “ Installation menu ” - “ IO Setup ” .

Information
With the growth program switchedon the “ offset ” or “ set value ” is calculatedby the growth program
( growth program).

9.5.1 Settings for Heating H1
9.5.1.1 Two-position control independent of the ventilation nominal value (factory setting)
Programming in installation menu
•
“ H1 Modus ” =
|
1
|
for two-point controller
•
“ H1 input ” =
|
0
|
for input “ E1 ” (i.e. like actual value for ventilation)
H1 Offset
H1 Offset
Heating switch-on point relatedto ventilation setpoint (i.e. offset setting in Kelvin)
Setting range: -10...+10 K
Factory setting: -2.0 K
H1 Hysteresis
H1 Hysteresis
Positive hysteresis value = Heating function
Relay
|
ON
|
as long as the temperature aroundthe hysteresis is above the switch-on
point.
Negative hysteresis value =
Cooling function
Relay
|
OFF
|
if the temperature aroundthe hysteresis is below the switch-on point.
Setting range: -10...+10 K
Factory setting: 0.5 K
Attention!
When setting a negative hysteresis, the function is inverted, i.e., “ Cooling function ”
Special function in which a device for cooling the room temperature is activated instead of a heater.
