Hygrothermostats

Snow-clearing by heating cables on roofs and access ramps requires the implementation of a system to optimize energy consumption. Dpstar provides a hygrothermostat which controls the outside temperature and the presence of humidity thanks to two sensors. This regulation system limits the energy needed for the efficiency of your installations and extend the lifetime of your heating elements.

The FX/CDM1 A hygrothermostat permanently checks for the presence of snow or black ice in gutters or access ramps. The heating cables are powered according to the outside temperature and the presence of humidity. The energy required is calculated by an interval timer switch.

Operation/Settings

°C  Temperature below which the regulator comes into operation.
Δt  Zone in which the regulator operates as an energy dispenser proportional to needs.

Example:
with “°C” = + 5°C and “t” = 10°C, if outside temperature:
+ 5°C : 0 % of energy
0°C : 50 % of energy
– 5°C : 100 % of energy

“T min” Time Base  This is the period of a cycle energised and de-energised in the operation sequence. Time can be set from 30s to 10 min.
Example with 40 % of energy:

“SEN” Sensitivity of the humidity sensor 
This setting makes it possible to vary the sensititvity of the snow detection circuit. Value “1“ corresponds to the greatest sensitivity to humidity.
