Azel SP-85 and 5 units of D-508F Floor Heating Thermostats: 5 ZONE CIRCULATOR PUMP CONTROL (SWITCHING RELAY) WITH PRIORITY FOR FOR HYDRONIC RADIANT FLOOR HEATING SYSTEMS AND 5 UNITS OF NON-PROGRAMMABLE DIGITAL FLOOR HEATING THERMOSTATS
The i-Link series 5-zone circulator pump
controller is operated by low voltage thermostats or any other low
voltage controllers having an SPST switching action.
The i-Link controller provides intermediate switching to permit up
to 5 circulators and a boiler operating control in a multi-zone hydronic
heating system.
Intelligent Linking System (i-Link) allows unlimited zone expansion
with additional i-Link controllers. Field selectable priority with timer
prevents freeze-ups in the event of a priority zone failure.
Unique power surge protection to avoid damage to the unit and ensure continuous control operation.
The panel provides EZ screwless terminal blocks for connections to
the thermostats. LED indicators on the front panel provides functional
status and easy troubleshooting. In addition, a system circulator is
turned on whenever any zone calls for heat.

D-508F: NON-PROGRAMMABLE DIGITAL SLAB SENSING THERMOSTAT FOR HYDRONIC RADIANT FLOOR HEATINGD-508F digital
non-programmable hydronic radiant floor heating heat only thermostat is
designed to control either ambient(air) temperature (A Mode) or floor
temperature (F Mode) or a combination of ambient temperature with floor
temperature limits(AF Mode). An auxiliary remote sensor is provided to
measure slab temperature in order to control the floor
temperature(within maximum and minimum limits in AF Mode). It can also
be used for sensing the outdoor temperature in A Mode.
FEATURES:
- Large LCD display
- Easy-to-Read Digital Multi-Display with backlit
which provides constant readout of two sensor temperatures(eg. ambient
and floor) and setpoint simultaneously, functional status and control
settings.
- Three temperature control modes:
A Mode : controls ambient temperature
F Mode : controls floor temperature. Also displays current ambient
temperature.
AF Mode: controls the ambient temperature and maintains the floor
temperature within the desired minimum limit for floor warming and
maximum limit for protecting floor coverings. Also, displays current
floor temperature.
- QuickSet feature allows instant setpoint adjustment without entering the SETTING mode
- Contemporary design
- Easy installation and setup
- Selectable display in °F or °C
- On/Off switch to shut off relay output or shutdown the thermostat at end of heating season for added security
- EEPROM memory retains control settings in the event of a power failure
- Lockout mode to prevent tempering by unauthorized personnel
- Sensor failure and out of range indications
- One stage heating application
- Backlit option: Auto (60 sec.)/OFF/ON
- Supplied with P-01 floor sensor with 10 ft lead
- Battery free
- RoHS(Restriction of Hazardous Substances) compliant means this thermostat is Eco- friendly
- Floor sensor included
