MiniWarden OVERVIEW
SeaSideAutomation, with over 20 years of technological leadership in Pool & Spa Chemical Control
Systems congratulates you on your selection of the MiniWarden Chemical Controller. MiniWarden is a
water chemistry control system with capabilities to control the pH and sanitizer on a pool, spa, fountain or
any other similar body of water. Using ORP (oxidation reduction potential) technology the control of
sanitizer takes into account the effects of pH and a pH lockout feature is also included for high pH
values.
Supporting both 110 and 220 VAC, the MiniWarden will control chemical feed equipment using relays to
keep the pool or spa water in balance. Water measurements are taken continuously while MiniWarden's
internal relay programing determines if chemical adjustments are needed. MiniWarden also contains a
selection for the sanitizer relay to be dry-contact which can be used for salt water chlorine generators and
solenoid valves that are controlled with a different voltage or a simple switch.
SYSTEM COMPONENTS
Simple and Advanced operating modes: SIMPLE: Cycle time control makes the MiniWarden very easy
to operate and only a few settings required for operation. ADVANCED: The original operating modes
allowing for very detailed and precise control.
CONTROLLER: MiniWarden is a microprocessor based, modular automation system that is
capable of continuous monitoring locally onsite or remotely offsite.
INTERFACE: MiniWarden uses a 16-button built in keypad, and an easy to read 80 character
liquid crystal display. The display’s internal back-light provides controller viewing in pool rooms with low
light conditions. Back-light illumination time can be adjusted to suit the operator.
MEMORY: MiniWarden is designed with nonvolatile memory which preserves all internal programming
in case of power loss. Internal memory is preserved for up to 10 years without having power applied.
RELAYS: MiniWarden includes 2 output relays for the control of pH and sanitizer.
SENSORS: ORP Sensor, pH Sensor, Temperature Sensor and Flow Sensor.
VOLTAGE: MiniWarden requires 120/220 VAC Input Voltage to operate.
SECURITY: MiniWarden is designed with a lockable enclosure and provides up to four levels of
password security protection (Admin, Tech, Service and Guest) for both local onsite and remote offsite
interaction with the controller with 10 passwords.
COMMUNICATION: MiniWarden can connect to the Internet for direct monitoring, setup, and data
interface via an Ethernet option (a WIFI bridge can be added for wireless).
DATA: MiniWarden will record up to 8192 lines of data with the built in internal memory.
OVERFEED PROTECTION: MiniWarden is designed with overfeed protection. Standard Overfeed
limits the amount of time a relay can turn on feed equipment in a 24-Hour period. Also includes a
setpoint overfeed limit that can be used to prevent chemicals from being fed onto the floor of the
equipment room by damaged feed tubes.
PROPORTIONAL FEED: Proportionally reduces the on-time as the measurement gets closer to the
set-point to prevent overshoot.
