Herpstat Humidity
?

Herpstat Humidity is designed to work with misting systems, foggers, and humidifiers to help
create a comfortable atmosphere for your animals. You can dial in a humidity range and the
Herpstat Humidity will attempt to maintain within that range by triggering your humidity device.
Misting systems and foggers get a time based control which first checks if the humidity level is
in
range before triggering which avoids overly damp conditions. We even created two user
settable/optional times that can be set that will force a misting cycle for animals that use misting
systems for drinking. Humidifiers can be run with constant regulation. The Herpstat Humidity
takes the worry out of handling sensitive animals. Why trust your enclosures to a $10 timer when
you can get true control and automation!

•Adjustable Humidity regulation from 10-90% RH

•Sensor accuracy: /- 2% RH (between 10-90% RH)

•24 hour or settable time period operation

•Adjustable duration (on time) from 2 seconds to 30 minutes

•Adjustable interval (time between sessions) from 3 minutes to 8 hours

•Two optional scheduled times to turn on

•High / Low humidity and temperature tracking helps monitor moisture system and enclosure
efficiency.

•Adjustable calibration allowing the user to digitally calibrate the sensor output to match other
equipment.

•All settings are retained in memory even if power is lost.

•Easy to read backlit LCD display.Power Outage detection / tracking

•Removable sensor for easy replacement if necessary.

Johnson A419 - Digital On / Off Thermostat



Digital Electronic On/Off Thermostat

The Johnson Controls A419 electronic temperature control combines keypad programming with
a liquid crystal display (LCD) to provide greater built-in control versatility. A large display
screen lets users check between setpoint and temperature at a glance, and a bright LED also
makes it easy to see relay status. An adjustable anti-short cycle timer prevents controlled
equipment from restarting immediately after shutdown.

Key Features
• Reliable Electronic Accuracy with a Liquid Crystal Display that clearly displays the current
sensor temperature and other functions.
• Versatile Setpoint and Differential adjustments that allow user to quickly and easily configure
the A419 to cut-in on temperature rise or drop in either the Cooling or Heating mode.
• Can be used for heating or cooling with the change of a jumper setting
• Easy Fingertip-Touch Programming that can be locked to deter unauthorized adjustments of the
control.
• Light Emitting Diode that indicates output relay status.
• Adjustable Anti-Short Cycle Delay that prevents the controlled equipment (e.g. Compressor)
from cycling on for up to 12 minutes after the A419 has cycled it off.
• Interchangeable Remote Sensor that may be mounted up to 800 ft (244m) from the A419.
• Sensor Failure Indication that alerts user to problems with the sensor circuit and operates the
controlled equipment either on or off according to user selected mode.
• Able to power up to 1500 watts of heating equiptment
• Compact, High Impact Plastic, NEMA 1 Enclosure with captive cover screws, suitable for
direct surface mount
• View Manual
