Installation Operation Maintenance

ControlsTrane THS01,THS02, THP01 andTHP02 Thermostats are directlyconnected to RTRM board(J7 connector).Trane THS03 and THP03 thermostatsare directly connected to RTRMboard (J6 connector).Install the electrical link between thethermostat (thermostat terminalstrip) and the unit (J6 orJ7 connector) in compliance withthe interconnection diagram. Thelow voltage wiring must not be laidin the same pipes as the powercables.The sizes and lengths of thethermostat connection wires aregiven in Table 39. The totalresistance of these control cablesmust not exceed 5 ohms. If theresistance exceeds this value thethermostat may not operate withthe same precision.Table 39 - Zone sensor wire andmaximum lengthWire size(mm²)Maximumwire lengh(m)0,33 450,5 760,75 1151,3 1852 300Unit controlled by BASEach unit must be equipped with aTCI-R board. A communication bus(twisted shielded pair) must linkeach TCI-R to the Trane Roof TopManager (RTM) or to thecommunication gateway (in thecase of an external BAS). Connectone temperature sensor to eachunit. LonTalk ® communicationinterface LTCl-R board allows ICScommunication between aReliaTel unit and LonTalk ®communication applications.Unit controlled by TrackersupervisorThe units must also be equippedwith the TCI-R communicationboard. One remote sensor isrequired on each unit for a constantflow volume. In the case of avariable flow installation(VariTrac) these sensors must notbe installed. A twisted shielded pairmust be used for thecommunication link. The mainfunctions of the Tracker supervisorare control of setpoints, timetablemanagement (Programming) anddisplay of faults.
