Installation Instructions

District heating and

d.h.w. controller

RVD110

RVD130

Installation

Place of installation

• In a dry room, e.g. the heat exchanger room

• Mounting choices:

- In a compact station

- In a control panel (in the front, on the inner wall,

or on a DIN mounting rail)

- In the sloping front of a control desk

Permissible ambient temperature: 0...50 °C

Electrical installation

• Local regulations for electrical installations must be

complied with

• Cable tension relief must be ensured

• The cables from the controller to the actuators and

pumps carry mains voltage

• The cables to the sensors should not be run parallel

to mains carrying cable (safety class II to

EN 60730!)

Permissible cable lengths

• For all sensors:

Copper cable 0.6 mm dia. 20 m max.

Copper cable 1.0 mm

80 m max.

Copper cable 1.5 mm

120 m max.

• For room units:

Copper cable 0.6 mm dia. 37 m max.

Copper cable ≥0.8 mm dia. 75 m max.

Mounting and wiring the base

Wall mounting

1. Separate base from the controller

2. Hold base against the wall. Marking “TOP“ must be

at the top!

3. Mark fixing holes on the wall

4. Drill holes

5. If required, knock out holes on the base for cable

entry glands

6. Screw base to the wall

7. Wire up base

DIN rail mounting

1. Fit rail

2. Separate base from the controller

3. If required, knock out holes on the base for cable

entry glands

4. Fit base to the rail. Marking “TOP“ must be at the

top!

5. If required, secure base (depending on the type of

rail used)

6. Wire up base

Flush panel mounting

• Maximum thickness: 3 mm

• Panel cutout required: 92 × 138 mm

1. Separate base from the controller

2. If required, knock out holes on the base for cable

entry glands

3. Insert base in the panel cutout from behind until

stop is reached. Marking “TOP“ must be at the top!

4. Push lateral tongues behind the front panel

(refer to illustration below)

2462Z06

Wrong Correct

Place tongues on both sides correctly – they may not be lo-

cated inside the cutout!

5. Wire up base. Make sure the cable lengths are

such that there is sufficient space to open the con-

trol panel door

Securing the controller to the base

1. Ensure correct position and location of levers by

turning the fixing screws (refer to illustration on the

lateral wall of the unit)

2522Z13

2. Insert controller in the base until stop is reached.

Marking “TOP“ must be at the top!

3. Tighten fixing screws alternately

Commissioning

Preparatory checks

1. DO NOT switch on power supply yet

2. Check wiring according to the plant connection

diagram

3. Check each motorized valve: see if

- it is correctly installed (observe direction of flow

indicated on the valve body)

- the manual lever is disengaged

4. Note with underfloor and ceiling heating systems! The limit thermostat must be set to the correct value. During the functional test, the flow temperature may not exceed the maximum permissible level (usually 55 °C). If it does, proceed immediately as follows: - Either close the valve manually, or - Switch off the pump, or - Close the pump isolating valve 5. Switch on power supply. The display must show the time of day.
