Com fort Operating Mode (Sun):
Press +/- button(s) to adjust the
desired setpoint.
Nigh t Setback Mode (Moon):
Sets the operating temperature to a lower point.
Use the +/- button(s) to adjust the setback temperature.
Time r (Clock):
Thermostat can be tied into an external timer to control system
operation.
Blinking sun indicates system is in Comfort Mode.
Blinking moon indicates system is in Setback Mode.

CONTrOl SETTiNgS AND PArAMETErS
J0:
°C/°F Temperature display section.
J1:
Hot/Cold regulation mode. Select Hot for Heating, Cold for cooling.
Hot:
opens actuator when temperature rises above setpoint.
Cold:
closes actuator when temperature drops below setpoint.
Cy:
Proportional Integral regulation time cycle, value in minutes
(default: 15 minute cycle).
This setting adjusts how frequently the control monitors the sensor
readings. Lower mass systems (frame floor applications) can lose heat
faster than high mass systems (slabs) and may require a faster cycle
time.
bp:
Proportional Integral regulation band amplitude value in degrees °C/°F
(default: 2.0°C/35.6°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
everyday.
Use this setting to allow the thermostat to cycle the circulator for 1
minute every day. This setting helps maintain lubrication during no-heat
periods.
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.
J7:
rEG (proportional Integral) or HYs (0.3°C Hysteresis) regulation type selection.
rEG
is preferred setting for use with radiant applications.
HYs
is preferred setting for use with forced air or other convection
systems.
Cp:
Proportional Integral regulation temperature compensation value in °C/°F
(default: 2.0°C/35.6°F).
Adjusts the calibration between the displayed temperature reading and
the calibrated temperature reading. Do not adjust this value unless
necessary.
Ao:
Air Sensor offset adjustment (default: no offset), display measure air sensor
value.
Adjust the display reading to match the air sensor reading.
Fo:
Floor sensor offset adjustment (default: no offset), display measure floor sen-
sor value.
Adjust the display reading to match the floor sensor reading.
FL:
Floor temperature LOW limitation (default: 5°C/41°F), effective only if floor
sensor present and set
J6
to
Air
.
This setting keeps the floor from dropping below the designated tem-
perature.
FH:
Floor temperature HIGH limitation (default: 28°C/82°F), effective only if floor
sensor present and set
J6
to
Air
.
This setting keeps the floor from rising above the designated tempera-
ture.

Press
OK
to reset to factory defaults.
