EGWS is mounted in the riser pipe some 0 5 1 m downstream of the mixing valve If an EGA strap on sensor is used it should be mounted on an un insulated part of the pipe Clean the pipe thoroughly so that the copper contact plate of the sensor makes good contact with the pipe Room sensor EGRL To achieve the best performance the following should be taken into consideration when mounting the room sensor e The sensor should be installed in a room which is typical of the building e The sensor should be placed on an inner wall of light building material The wall must not beheated by for example uninsulated heating pipes behind it e The room should be of sufficient size for the temperature not to be adversely affected by people or machinery e The radiators in the room should not have thermostat valves If they have they should be turned to the largest value possible e The room sensor should be placed so that the air can flow freely around it e The room sensor should be placed within 10 m from the nearest radiator but not right above it Actuator M44 M5 M15 M42 Mounting instructions are supplied with the actuator mounting kit OFL 3563 000 2000 01 Base plate TAC 2000TP Cover es AT p D de a Aa D Figure 1 Figure 2 Wiring Connect the cables to the controller according to the wiring diagram see figure 3 on
