2 COMFORT Operating conditions 2. Operating conditions Pumped liquids • Thin, clean, non-aggressive and non-explosive liquids without solid particles or fibres • Cooling liquids, not containing mineral oil • Domestic hot water • Softened water. The kinematic viscosity of water is 1 mm2/s (1 cSt) at 20 °C (68 °F) If the pump is used for a liquid with a higher viscosity, the hydraulic performance of the pump will be reduced.
3 Functions COMFORT 3. Functions COMFORT with AUTOADAPT AUTOADAPT in heating systems regulated with a thermostatic regulating valve COMFORT BA PM and BXA PM models have the following operation modes: • AUTOADAPT • temperature control mode • continuous 100 % mode. In systems including a thermostatic regulating valve, choose a COMFORT pump without the AUTOADAPT function.
3 COMFORT Functions Event log function The AUTOADAPT function incorporates an event log that learns the scheme of demand for hot water in the domestic hot-water system. Via the event log, the pump predicts when to start circulating hot water. Date The event log function stores the weekly tapping events in the system. The hot-water consumption pattern for two weeks is stored in the event log. See example.
3 COMFORT Continuous 100 % mode The regulation of the COMFORT AUTOADAPT models is based on temperature control. The operating range of the pump is kept within a calculated temperature range. This means that the pump operates in an average temperature area providing the maximum comfort and saves energy at the same time. Functions Temperature control mode for AUTOADAPT (BA, BXA) variants The pump is running continuously at full speed without any control.
3 COMFORT Operating panel COMFORT BDT and BXDT PM models have the following functions and operating modes: • Continuous 100 % mode. Set the pump to run in continuos 100 % mode with no defined operating periods. • Digital timer. Use the default operating schedule or customise the pump's operating periods. Continuous 100 % mode 1 9 2 8 3 The pump is running continuously at full speed without any control.
Construction 4 COMFORT 4. Construction Grundfos COMFORT PM circulator pumps are available in various pump housing versions and lengths incorporating isolating and non-return valves or prepared for subsequent fitting of such valves. The motor can be separated from the pump housing, enabling easy maintenance and replacement. The rotor bearing is self-adjusting and lubricated by the pumped liquid.
4 COMFORT Union nut The pump housing is designed in such a way that a high hydraulic efficiency is achieved when the energy produced by the impeller is converted into pressure. The pump housing thread enables connection to standard pipe dimensions. The union nut ensures that motor and pump housing are tightly connected. Thanks to the thread type, the seal ring is pressed evenly over the entire seal face.

5 COMFORT Performance curves 5. Performance curves Curve conditions The guidelines below apply to the performance curves on the following pages: • Test liquid: airless water. • The measurements for COMFORT PM have been made at a water temperature of 20 °C (68 °F). • All curves show average values and must not be used as guarantee curves. If a specific minimum performance is required, individual measurements must be made.
