Pressing the UP button while in the VIEW menu
starts operation of the Hot Tub for the time set.
To Stop operation press the DOWN button until
the time shows OFF.
Application Mode 5 configures the setpoint control for floor
warming and floor heating applications using pulse width
modulation. Floor warming is not necessarily designed to
heat the room, but to make the floor feel warm to the touch.
This is common especially in bathrooms. For bathroom
applications, Relay 2 can also heat a towel warmer radiator
while in the occupied period. A sensor must be located
within the slab between the heating pipes. The setpoint
control allows a Floor temperature to be set for the occupied,
unoccupied, and away events.
Application Mode 5 - Floor SECTION E
Relay 1 Operation
Relay 1 operates using pulse width modulation to maintain
the load at the Occupied, Unoccupied, or Away temperatures
depending on the schedule and scene.
Relay 2 Operation
Relay 2 operates continuously while in the occupied period
to heat a towel warmer.
Relay 2 remains off during the unoccupied and away
periods.
Occupied Time
The setpoint control can temporarily override the scheduled
temperature and operate at the occupied temperature on
a timer.
Press the Up or Down buttons while in the View menu
to set the amount of time that the occupied temperature
should remain in effect.
To use this feature, a programmable schedule must be set
or the schedule be set to normally operate at the unoccupied
setting. When the schedule is set to unoccupied, the
setpoint control operates at the unoccupied setting until
activated.
The length of time the setpoint remains at the occupied
temperature is preset by the Run Time Occupied item
located in the Scene menu.
To cancel the temporary occupied time, press and hold
the Down button until the display shows off, at which point,
the setpoint control returns to the schedule.
Application Mode 6 - Pool SECTION F
Application Mode 6 configures the setpoint control for pool
heating using pulse width modulation. A sensor is located
in a temperature well on the pool return recirculation pipe.
The pool can have an occupied temperature. During the
unoccupied and away periods, the pool is not heated.
Relay 1 Operation
Relay 1 operates using pulse width modulation to maintain
the load at the occupied temperature. Relay 1 remains off
during the unoccupied and away periods.
Relay 2 Operation
Relay 2 operates continuously while in the occupied period
to provide constant circulation and reduce temperature
swing.
Relay 2 remains off during the unoccupied and away
periods.
Relay 2 operates to provide pool filtration.
Pool Filtration
The pool application includes filtration logic to operate the
pump controlled by Relay 2. The Relay 2 Pump On setting
allows installers to choose a time at which Relay 2 starts
a pump for filtration of the pool. The Relay 2 Pump Run
Time setting determines how long Relay 2 should run the
pump for filtration.
Mode of Operation
The pool mode of operation can be set to either Heat or
Off. While set to Off, Relay 1 and Relay 2 remain off. The
OFF setting should only be used when the pool is drained
or there is no possibility of freezing. Power should never
be removed from the setpoint control as this will result in
an error message on the tN4 system.
