Room Temperature Unit (RTU) 062, 063
A single RTU may be connected to the Boiler Control 262 in order to provide the control with indoor temperature
feedback for a single zone heating system in Mode = —1— (Refer to Essay E 002). When multiple zones are
required for the heating system, use either a tekmar Zone Control or, through the boiler demand input, on/off
zone control. When using an RTU, several items related to the heating system are no longer available in the
control’s User Interface. These items are available only in the RTU’s User Interface. Also, the number of items
that are available on the RTU depends on the type of RTU that is connected to the control.
