OUTDOOR AIR SENSOR

RAYPAK MODULATING TEMP CONTROL

Mode 8 – This mode is for remote firing control of the heater via an external sequencer such as the Raypak TempTracker MOD+. The Boil Max setting is the heater shutdown temperature (max temperature). The heater is enabled via dry contact at the Enable/Disable connection at the low voltage terminal strip, and the fir- ing rate is controlled by a 0-10 VDC signal from the external sequencer. A control signal of ≥0.5 VDC equates to minimum fire, and a signal of 10 VDC equates to 100% firing rate.

NOTE: For Modes 7 and 8, connect to pins 13 and 14 on the low-voltage panel. See page 21. Use these modes for systems using an external signal.

Definitions

NOTE: The defined terms are not active in all modes of control operation.

%OUT - Current percent modulation rate of heater.

BOIL DSGN - Design boiler water temperature used in heat loss calculations.

BOIL MASS - This setting allows adjustment in the field for high or low thermal masses; High thermal mass (setting=3) provides slower reaction, lower ther- mal mass (setting=1) provides faster reaction.

BOIL MAX - Highest outlet water temperature that the control is allowed to use as a target temperature. BOIL MIN - Lowest outlet water temperature that the control is allowed to use as a target temperature.

*

*Maximum 4 times the pipe diameter or 12”, whichever is less.

External Direct Drive

BOIL ON - Accumulated runtime of heater (up to 999 hours, then resets to 0).

BOIL OUT - Actual heater outlet water temperature. BOIL START - Starting boiler water temperature. BOIL SUP - Actual system supply water temperature. BOIL TARGET - Target temperature that the heater is trying to maintain.

‘BURNER’ DELAY - Holds control output at ignition setting from the start of the ignition sequence to the specified burner delay time (0 to 3:00 min.).

DEM 1 - Indicates 24 VDC signal has been supplied to the H+D terminal.

DEM 2 - Indicates 24 VDC Flame Proof signal is pres- ent.

DIFF - The operating differential of the heater; The heater outlet water temperature is allowed to rise above the BOIL TARGET temperature by 1⁄2 of this dif- ferential before the heater shuts off. For example, if the heater target temperature is set to 160°F (71°C) and the differential is set to 10°F (5°C), on temperature rise, the heater will shut off at 165°F (74°C). Once the heater shuts off, it will not come on again until the tem- perature falls to 155°F (68°C).
