6 Channel Underfloor Heating Controller
Configuration Tables
| Doorway / InSite Code | Label | Description | Units | Default Value | Range |
C1 |
CHNL |
Heating channel to be configured |
- |
- |
1 to 6 |
C2 |
SCAL |
Sensor calibration (used for calibrating the sensor input, if required) |
- |
0 |
-5 to 5 |
C3 |
SENN |
Current channel sensor number. A sensor input is associated with each heating channel (e.g. SENN=1 relates to temperature sensor on input A), but a temperature sensor can also be shared with other control channels |
- |
0 |
1 to 6 |
C4 |
PRD |
Current heating channel stroke/minimum ON time (e.g. PRD=6 is 60 sec). The heating channels are set for time proportioning control |
secs/10 |
6 |
1 to 240 |
C5 |
DLY |
Current channel interlock delay. Negative value= delay on operation, positive value=delay off operation |
- |
0 |
-60 to +60 |
C6 |
SPTY |
Setpoint type0: Heating channels use their own setpoint determined
on parameter K1 (SPOC) |
- |
0 |
0 to 1 |
C7 |
HTSC |
Heat source. The heat source parameter determines where the heat demand is sent to (e.g. boiler controller, VTC secondary circuit controller...etc) |
- |
- |
0 to 8255 |
C8 |
CLSC |
Not used on this application |
- |
0 |
0 to 8255 |
C9 |
OCDS |
Occupancy destination. This parameter can be used to send an occupancy demand link to another controller |
- |
0 |
0 to 8255 |
C10 |
HTCT |
Heating demand sent as CT |
- |
0 |
0 to 100 |
C11 |
CLCT |
Not used on this application |
- |
0 |
0 to 20 |
C12 |
SNDT |
Not used on this application |
- |

0 to 1 |
C13 |
FPLS |
Fixed plot scaling (do not change setting) |
- |
1 |
0 to 1 |
