District Heating Controller

for one heating circuit and d.h.w.

RVD110

RVD130

• Controller for use in district heating substations and district heating plants.

Control of a pump heating circuit. Domestic hot water (d.h.w.) heating in in-

stantaneous systems or with a storage tank

• 8 preprogrammed plant types with automatic assignment of the functions re-

quired for each type of plant

• Direct analog setting of normal setpoint, other settings are digital using oper-

ating lines

• Operating voltage AC 230 V, controller for flush panel mounting measuring

96×144 mm, conforming to CE

• Optional remote operation via room unit

Use

• Plant:

Heat exchanger in the district heating substation

• Buildings:

Residential and non-residential buildings with own district heating connection and

d.h.w. heating

• Types of space heating systems:

All common heating systems, such as radiator, convector, underfloor and ceiling

heating systems, or radiating panels

• Types of d.h.w. heating systems:

− D.h.w. storage tanks or instantaneous systems

− Common or separate heat exchangers for heating circuit and d.h.w. heating

Acquisition of measured values • • • • Flow temperature sensor: LG-Ni 1000 Ω at 0 °C (e.g. QAD22) Outside sensor: LG-Ni 1000 (QAC22) or NTC 575 (QAC32) Primary return temperature sensor: LG-Ni 1000 or Pt 500 Room temperature: with a room unit QAW50 / QAW70 or room temperature sensor QAA10 If different types of sensors are used, the controller automatically identifies the type of sensor connected.

Time switch programs To provide automatic operation of the heating system, the controller features a weekly program with 3 heating periods that can be adjusted on a daily basis. Another weekly program is available for the release of d.h.w. charging. Pump kick The pump kick is adjustable for the heating circuit pump, the d.h.w. charging pump, and the circulating pump. The pump kick is made once per week and lasts 30 seconds. The function can be deactivated, if required.

D.h.w. heating In addition to heating circuit control, the RVD110 / 130 provide control of d.h.w. heating in the following types of plant and d.h.w. systems: Plant type RVD110 RVD130 D.h.w.

The entry or readjustment of all the other setting parameters, activation of optional functions, and reading of actual values and statuses is made using the operating line principle. An operating line with an associated number is assigned to each parameter, each actual value and each function that can be selected. One pair of buttons is used to select an operating line and one pair to readjust the display. These buttons are located behind a hinged cover.
