1. Application.

The UMS-4PS weather compensating controller is a microprocessor device designed

for weather compensating central heating temperature control in the installations

powered by a central heating system. The temperature in the central heating

circulation is maintained by controlling the servomotor of the mixing valve.

The controller is equipped with the output designed for controlling the central heating

pump, the temperature of installation water decrease input and the heating turn-off

input. The construction of the device makes it possible to connect parallelly any given

number of UMS-4PS controllers which means that one boiler or central unit may be

connected independently to many central heating systems.

2. Connection.

Before turning the power on, the cables powering the controller, the servomotor of the

mixing valve and the cables powering the central heating pump should be connected

to the appropriate sockets. The outside temperature sensor may be connected

parallelly to any given number of UMS/UMP controllers, bearing in mind that

appropriate contacts should be connected to the suitable contacts of the controller.

Each UMS-4PS controller requires a separate central heating temperature sensor.

Detailed connection scheme is presented in the picture 3.

CAUTION!

Before plugging in the controller make sure that the wiring system is

properly grounded.

3. Operation.

The front panel of the controller (picture 1) contains:

1 – Display.

2 – Servomotor of the mixing valve indicator (opening).

3 – Servomotor of the mixing valve indicator (closing).

4 – temperature sensors and additional features control inputs connector

5 – (-) button used for selecting and changing parameters.

6 – OK button used for changing and accepting parameters.

7 – (+) button used for selecting and changing parameters.

8 – (*) button.

9 – central heating pump control connector.

10 – central heating pump control input indicator.

11 – power and the mixing valve servomotor control connector.
