Functions Main functions · Control of the water temperature through 3-position control of a seat or slipper valve · Minimum or maximum limitation of the flow or return temperature, or minimum limitation of the boiler return temperature Other functions · Outside temperature compensation · Remote setpoint adjustment · Setpoint changeover via external contact, can be selected to provide temperature setback or legionella function · Frost protection · Load-dependent switching contact (e.g.
PAGE 3
· Control with boost The following settings are required: · Setpoint · Control mode: A choice of 4 PI modes are available to suit the type of controlled system (refer to chapter “Mechanical design”) · P-band Mode of operation as a limiter The control signals of the heating zone controller (RVL4…, RVP3…, RVP2…) are passed to the RLE132 which acts as a limiter. Minimum limitation 1. 2. 3. Maximum limitation 1. 2. 3. Outside temperature compensation If the temperature (e.g.

This makes possible legionella protection in DHW heating systems. With the help of a 7-day time switch, the DHW is periodically heated up to the required temperature. Setting A slider is provided to set the temperature by which the nominal setpoint shall be lowered (ECO) or raised (boost). The setting cannot be accessed by the user. Switching contact The switching output (terminals Q13–Q14) enables a plant element to be switched depending on demand, or a limitation alarm to be generated.

For mounting, a protection pocket is provided; the controller is inserted and snaps on. Engineering notes The controller is supplied complete with Mounting and Installation Instructions. Mounting notes Ensure that the local safety regulations are complied with. Suitable mounting locations are the following, depending on the application: · Flow temperature control: - In the heating flow; immediately after the pump if the pump is mounted in the flow - In the heating flow; approximately 1.
