ASCOM Heat Sink Temperature always 0.0???

astroman133

I have an ASI178MM and am using ASCOM 6.2 with the ZWO ASCOM Driver V1.0.2.8.

When I connect to the camera and read the HeatSinkTemperature property the returned value is always 0.0. Is this normal?

I would expect that this property would return a reasonable value or throw an exception if the value is not available, per the ASCOM standard.

Thanks,

you should read CCDTemperature

Sorry, but you did not answer my question.

I am reading the CCDTemperature property, but I am also reading the HeatSinkTemperature property to allow me to control how the camera temperature is warmed up, since I don't want to continue to try to warm up the sensor above the HeatSinkTemperature.

I would expect that reading the HeatSinkTemperature would throw an exception if it is not supported, rather than to always return the same, unreasonable value.

Per the ASCOM Developers Help documentation, the driver should throw a NotConnectedException when a client app attempts to read the HeatSinkTemperature property value and the data is unavailable.

As it is, I have a hack in my code to ignore the HeatSinkTemperature, specifically for ZWO hardware.

thanks, our camera don't have sensor on heat sink

so we should throw one exception

we will do that in our next version
