9 Temperature regulation
It is advised to foresee an automatic regulation according to the heating needs.
It is necessary to foresee a regulation per room or per zone.
The regulation occurs completely by the electric power supply of the units.
We advise the use of a resultant regulation for the complete installation, regardless global
local or zonal heating. This regulation consists of an electronic regulator and a resultant
sensor registering the energy radiated by the unit(s) and controlling the installation on the dry
resultant temperature being a better comfort criterion than only the air temperature. The
regulator contains a lowering of the occupation temperature : therefore is it necessary to use
a dry contact from a clock or relay.
We advise to respect the instructions concerning the material and particularly :
- To position the sensor at about 1.5m from the ground between two appliances so that it
receives a homogeneous radiation,
- To insulate the sensor from the wall on which it can be found in order to avoid the cold
radiation of the wall through the interposition of an insulating material (glass wool, wood, etc.),
- The connection between sensor and regulator must be made out of armoured cable or
phone cable, 2 pairs.
- In any case, do not put these wires in the cable path which already contains many wires
carrying energy
Material supplied by GAZ INDUSTRIE :
- Regulator with sensor Infracapt 20.10.
- Energystat, model Energystat 10 (1 zone), Energystat 12 (2 zones).
- Standard regulation box or specific on demand.
d/ Option " Failure signal transmission "
This option allows the transmission of the failure signal (on each individual unit or per group of
units) to a control panel or the GTC system.
To ensure safe working, the transmission of the failure signal happens by means of a dry
contact controlled by a relay incorporated inside the unit (3).
In order to avoid undesirable shutdown at each ignition attempt, it is recommended to delay
the failure signal of the control panel or GTC by 30 seconds.
The unit is delivered in standard version with a closed contact, if you want open one, you may
ask us at the order.
