DHW temperature is adjusted as follows: To increase temperature, turn the handle on the thermostatic controller to select a higher number. To decrease temperature, turn the handle on the thermostatic controller to select a lower number. AQ110886477411en-020601/ LUK41500 12 | © Danfoss | 2022.11... - Page 13 The controller is a self-acting flow controller with integrated control valve. The controller closes when set max. flow is exceeded and can be used in combination with Danfoss electrical actuators with or with out safety function. Spring return motor can be used as safety function by power failure.
