The difference between the two coils, is the power output that can be achieved. This means both can be
mounted as pre heating and post heating, depending on the specific project requirement. The additional PCB
for external accessories (ATE00DPUA) is required in order to enable communication between controller and
external heaters. In the Astra Web selection software for Modular T Pro version, the additional temperature
probe and optional PCB for accessories are automatically added when an electric heater is selected.
5.3.2.4. Water pre-heating coil
A heating coil is available as accessory as pre heating. The coil is mounted outside the main module and it
must be ducted. Following table summarizes main technical data for pre heating water coil.
