Room Occupied and Unoccupied

The Room setting is the desired temperature of the building .

When a programmable schedule is used, there are both Room

Occupied and Room Unoccupied settings available . When the

programmable schedule is turned off, only the Room setting

is available .

Indoor Sensor Not Installed

When an indoor sensor is not connected to the control, the

Room setting operates as a parallel shift of the heating curve .

This allows fine tuning of the heating system . If the Room set-

ting is set above the Indoor Design setting, the entire heating

curve is shifted higher, resulting in longer heat on times being

calculated . Similarly, if the Room setting is set below the Indoor

Design setting, the entire heating curve is shifted lower, resulting

in shorter heat on times being calculated .

Indoor Sensor

Installation of an optional Indoor Sensor will provide better

temperature control compared to no indoor sensor installations .

When installed, the control automatically adjusts the heating

curve up or down to so that the ambient air temperature

reaches the Room Target . If the ambient temperature exceeds

the Room Target by 1°F (0 .5°C), the control sets the Heat On

time to zero and turns off the steam boilers .

Indoor Sensor Options

The control is compatible with indoor sensor models 076, 077

and 084 .
The temperature accuracy within the building can be improved

by installing a square number (4, 9, 16, 25) of sensors wired in

series-parallel to the auxiliary sensor input .
