I've recently bought a Victron Atlas Combi (12V 800W) for my friends from Ukraine.
Unfortunately the device came without a temperature sensor. The manual says, there must be one, temperature sensor type is specified as V.T.S. (Victron Temperature Sensor).
1. Will the modern temperature sensors for Multiplus/Skylla work with Atlas Combi ?: https://www.victronenergy.com/live/temperature_sensors
2. Is there a way to make the charger charge without the sensor (now it does not charge but shows no failure when no sensor connected and the jumper HD6 set to ON) ?
BTW. In Ukriane they have electricity now only at night for c.a. 4H (september 2022). Victron products are like blessing for them now. The goal is to run heating pump for few hours more. Atlas Combi, though an extra old device is exactly what should help them survive the winter.
