T775R Series 2000 Electronic
Stand-Alone Controller
PRODUCT DESCRIPTION
The T775 electronic stand-alone controllers are the next
generation of commercial and agricultural controls
capable of remote sensing of temperature and providing
switched and/or proportional outputs to various types of
loads. A built-in time clock is standard.
A Reset function is available for all T775R models where
the Sensor B temperature (e.g. outside temperature) is
used to provide reset control for the Sensor A
temperature (e.g. boiler). For example, as the outside
temperature gets colder, the setpoint temperature
automatically adjusts to save energy.
Three T775R models have analog (modulating) outputs
for actuator and motor control.
IMPORTANT
The T775R is an operating control, not a limit or
safety control. If used in applications requiring
safety or limit controls, a separate safety or limit
control device is required.
Table 1. T775R Controller Configurations.
a
All models include a digital input for use with the disable or setback option.
b
The modulating (analog) outputs are 4-20 mA, 0-10 Vdc, 2-10 Vdc, or Series 90 selectable.
c
Each floating output eliminates two SPDT relay outputs.
d
The T775R2043 can support a high/low modulating limit at Sensor B for temperature control at Sensor A.
