Temperature control
The cooling power and heat dissipation capability of the Goldeye is limited.
Therefore, the temperature difference achievable by the TEC is limited as well.
Table 49 below displays the maximum temperature difference, and the maximum
power necessary to achieve that.
Temperatures and values
Model 1 2 3 4
G ‐ 008 +20 °C * +25 °C (Default) +35 °C +50 °C
G ‐ 032 +5 °C +20 °C (Default) +35 °C +50 °C
G ‐ 032 Cool ‐ 20 °C (Default) ‐ 5 °C +10 °C (n/a)
G ‐ 033 +5 °C +20 °C (Default) +35 °C +50 °C
* The first temperature setpoint may be set lower than +20 °C. However if the
sensor temperature is lower than the ambient temperature, especially in humid
environments, condensation may occur.

Example for Goldeye G ‐ 033
For this example, we assume that during operation, the housing temperature of a
Goldeye G ‐ 033 has leveled at approx. +48 °C.
Since the temperature difference achievable by the G ‐ 033 is 25 K, the setpoint at
+20 °C cannot be reached.
Thus, the G ‐ 033 will switch to the lowest possible setpoint at +35 °C.
Example for Goldeye G ‐ 032 Cool
For this example, we assume that during operation, the housing temperature of a
Goldeye G ‐ 032 Cool has leveled at approx. +35 °C.
Since the temperature difference achievable is 60 K, the lowest setpoint at ‐ 20 °C
can still be reached.
Thus, the G ‐ 032 Cool will switch to the lowest defined setpoint at ‐ 20 °C.
