DSL-520P ZONE THERMOSTAT
INTRODUCTION
The nonprogrammable DSL-520P zone thermostat is the exclusive thermostat used with the
SlimZone Premier (SZP) system. The system will not function with any other thermostat.
The DSL-520P is a fully communicating thermostat which is powered by the SZP control mod-
ule and is constantly exchanging data with the control module to optimize control of the zoned
environment. It represents the most advanced solid-state, microprocessor temperature control
on the market today.
The thermostat has been designed to provide accurate control and display of room temperature,
and normally displays room temperature, mode of operation and whether cooling or heating is
currently on.
Your new thermostat uses an adaptive control routine, based on Fuzzy logic, to determine the
heating or cooling load of the area in which it is installed. The routine calculates the load by
evaluating recent room conditions (from the sensor within the thermostat or connected remote
)
sensor
and reactions to heating and cooling. The load factor is then used to determine when
your equipment should be activated and for how long, providing optimum control and econo-
my.
