Correction factor cS The °C display shows the actual temperature at the unit's control sensor ±0.1°C. This temperature does not correspond directly to the temperature in the circulator’s bath and even less to the temperature of any external connected system. The temperature difference is determined by measuring the actual current temperature using a suitable measuring device (calibrated or gauged thermometer).
Do not use steel wool. It is abrasive and will lead to rusting. Algae We recommend the use of Chloramine-T, 1 gram per 3.5 liters. Checklist 2100/2150 Unit will not start. Check for fault conditions. Unit made need a reset.
