Trane THS01,THS02, THP01 and THP02 Thermostats are directly connected to RTRM board

(J7 connector). TRANE THS02 and THP03 thermostats are directly connected to RTRM board

(J6 connector).

Install the electrical link between the thermostat (thermostat terminal strip) and the unit (J6 or J7 connector) in compliance with the interconnection diagram. The low voltage wiring must not be laid in the same pipes as the power cables.

The sizes and lengths of the thermostat connection wires are given in Table 29. The total resistance of these control cables must not exceed 5 ohms. If the resistance exceeds this value the thermostat may not operate with the same precision.
