| Contact Rating |
1/2 HP @ 240 Volts AC, 50/60 Hz per zone/channel;
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) |
| Failsafe Setpoint | 20° C (68° F) factory default setting, user-adjustable from 5° to 20° C (41° to 68° F); the failsafe setpoint is used at install time prior to connection of a 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 |
| Communications |
| Cresnet | Cresnet slave mode |
| Connections |
| 1 – 8 | (8 sets of 3) Captive screw terminals;
Comprises (8) zone valve control outputs with isolated common (C), normally closed (NC), and normally open (NO) terminals;
Each output provides one SPDT relay rated 1/2 HP @ 240 Volts AC, 50/60 Hz |
| MAIN | (3) Captive screw terminals;
Main valve control output with isolated common (C), normally closed (NC), and normally open (NO) terminals;
Provides one SPDT relay rated 1/2 HP @ 240 Volts AC, 50/60 Hz |
| NET | (2) 4-pin detachable terminal blocks;
Cresnet slave port with hardwire parallel pass-through |
| TEMP SENSE 1 – 8 | (8) 2-pin detachable terminal blocks;
Comprised (8) zone temperature sensor inputs;
Each input accepts one sensor, model CHVI-RTS-1G-SM-W, CHVI-RTS-1G-N-W, or CHV-RTS (sold separately);
Requires a dedicated low-capacitance twisted pair wire per zone (<7 nF per run);
Supports wire lengths of 76 m (250 ft) using CAT3 or 152 m (500 ft) using CAT5;
Thermostat wire is not recommended, but may be used if necessary at lengths up to 30 m (100 ft);
Refer to the DIN-1TSTAT8 Installation Guide, Doc. # 7950, for additional wiring guidelines |
| Controls & Indicators |
| 1 – 8 | (8) Red LEDs and (8) pushbuttons, each button toggles the corresponding zone 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 |
| NET | (1) Yellow LED, indicates Cresnet communication with the control system |
| RESET | (1) Recessed pushbutton for hardware reset |
