24v for use with CP ContactorPro Panels (CP-50/100/200)

To enter the parameter menu, press and hold the OK button for 5 seconds.

• Use the +/- keys to select the installation parameter to be adjusted.

• Press OK to toggle the parameter setting or to edit its value. When the value begins to blink, use the

+/- keys to adjust its value. Press OK to select the adjusted value.

• Toggle to “End” and press OK to exit the installation parameter menu.

• Parameters (Only Bold apply to Outdoor Patio Heating)

• J0: °C/°F Temperature display section.

• J1: Hot/Cold regulation mode. Select Hot for Heating, Cold for cooling.

• Cy: Proportional Integral regulation time cycle, value in minutes (default: 15 minute cycle).

• bp: Proportional Integral regulation band amplitude value in degrees °C/°F (default: 2.0°C/3.6°F).

• J4: NO/NC Normally Open or Normally Close actuator selection.

 NC: If using an isolation relay and/or a relay box.

 NO: if connecting to a Watts Zone Valve control.

• J5: Select PMP (Pump Maintenance Program) to perform a 1 minute exercise every day.

• J6: Air: Air (room) setpoint. Displays air temperature with floor low (FL) and high (FH) limits.

 Flr: Floor (external sensor) setpoint. Displays floor temperature

without floor low/high limits. Air temperature is not a control
boundary.

Î Air temp is not used because the T-stat is mounted INSIDE and the

area to be monitored is OUTSIDE and monitored with Floor Sensor
Only

• J7: rEG (proportional Integral) or HYs (0.3°C Hysteresis) regulation type selection.

• Cp: Proportional Integral regulation temperature compensation value in °C/°F

• (default: 2.0°C/3.6°F).

• Ao: Air Sensor offset adjustment (default: no offset), display measure air sensor value.

• Fo: Floor sensor offset adjustment (default: no offset), display measure floor

• sensor value.

• FL: Floor temperature LOW limitation (default: 5°C/41°F), effective only if floor

• sensor present and set J6 to Air.

• FH: Floor temperature HIGH limitation (default: 28°C/82°F), effective only if floor

• sensor present and set J6 to Air.

• CLr: Press OK to reset to factory defaults.

• End: Press OK to exit installation parameters.

DualTemp Digital Thermostat

Dimensions: 3-3/8" x 3-3/8"

The Watts Radiant DualTemp thermostat has the ability to sense
the temperature of the air, fl oor or a combination of air and fl oor.
Each DualTemp comes with an internal air sensor. An OPTIONAL
external 10k sensor which allows detection of fl oor temperatures may
be ordered separately. The external sensor does not have to be used if
the DualTemp is to detect air temperatures only.

Installation & Operation

To mount the thermostat remove the thermostat cover by removing the
white Screw Cover (located in the center of the thermostat cover) and
the Cover Screw. Secure the Base Unit to the wall. Be sure to feed the
electrical wiring (18-3 or 18-4) through the provided slot in the Base Unit
and connect to appropriate terminal block(s). Replace the Cover, Cover
Screw and Screw Cover.

If fl oor sensing is desired, make sure the fl oor sensor is connected to
the corresponding fl oor sensor terminals (labeled NTC, the fi rst two
terminals on the right terminal block). It may be necessary to adjust the
J6 setting. See wiring diagrams for details.
