If the room temperature is too low with your Viessmann Heat Pump, you should: * Vent the heating circuits. * Check the throughput of affected heating circuits, ensuring a temperature differential of approximately 8 K between the heating flow and return. * Increase the set room temperature for standard mode and match the heating curves. * Hydraulically balance the connected heating circuits. * Check the outside temperature sensor. * Enable heating operation via the integral instantaneous heating water heater (if installed).
