Overview
The DIN-1TSTAT8 is an 8-zone thermostat designed for use with radiant heating systems.
Customized control and scheduling is also possible. The use of remote temperature sensors
eliminates the need for a separate thermostat on the wall in each zone.
The DIN-1TSTAT8 is for heat-only applications using radiators or radiant floor heating. It
controls the heating valve for each zone via eight SPDT relay control outputs (one per zone). A
ninth main valve control output is also provided. Each relay includes normally open and normally
closed contacts, and is rated for 1/2HP at 240VAC, 50/60Hz.
A Crestron® control system connection allows temperature adjustments on each zone from
virtually anywhere by using a Crestron touch screen,handheld remote,mobile app, or computer.
The DIN-1TSTAT8 requires a Crestron control system to function. The heating setpoints for each
zone are set by the user through the control system and then stored in memory on the DIN-
1TSTAT8. In the event a user setpoint is lost, a failsafe operating mode takes over to keep the
space heated at a preset temperature until the user setpoint is restored from the control
system.
NOTE: A complete system requires custom commissioning by a Crestron authorized installer
and programmer. Contact your Crestronrepresentative for more information

Provides eight SPDT heat zone valve control outputs and one SPDT main valve control output
Temperature Sensing
Measurement Range 0° to 43°C (32° to 110°F)
Temperature Tolerance ±0.5°C (±1°F) over full range;
+0.1°/-0.4°C (±1°F) at room temperature
Setpoint Range (Heat
Only)
3° to 32°C (38° to 90°F)
Temperature Offset ±3°C (±6°F); in steps of 0.1° per temperature sensor input
Failsafe Setpoint 20°C (68°F) factory default setting, user-adjustable from 5° to 20°C (41° to

control system, and during runtime if the normal setpoint stored in memory
gets corrupted; reverts to the normal setpoint once a value is received from the
control system
Main Valve Delay 5 minutes factory setting, adjustable from 0 to 5 minutes

output on and off (press and hold 10 seconds for test call), each LED indicates
the corresponding zone output is on (flashes with heat call, steady without heat
call)
MAIN (1) Red LED and (1) pushbutton, button toggles the main output on and off
when held 10 seconds, LED indicates the main output is on (flashes with heat
call, steady without heat call)
SETUP (1) Recessed pushbutton and (1) red LED for Cresnet TSID (touch-settable ID)
PWR (1) Green LED, indicates device is powered via Cresnet
