IMPORTANT WARNING AND SAFETY INSTRUCTIONS
MiniWarden Manual • 530-205-4520 • 5
, 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 240 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.
MiniWarden Plus
When adding the PW-Plus communication module, the software feature set will also be updated. Where
there are differences that will be pointed out.
System Components
tCONTROLLER: MiniWarden is a microprocessor based, modular automation system that is
capable of continuous monitoring locally onsite or remotely offsite.
tINTERFACE: 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.
tMEMORY: 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.
tRELAYS: MiniWarden includes 2 output relays for the control of pH and sanitizer.
tSENSORS: ORP, pH, Temperature, flow and optional free chlorine sensors.
tVOLTAGE: Requires 120VAC input voltage in North America and 240VAC input voltage in Europe.
tSECURITY: 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 4 passwords.
tCOMMUNICATION: MiniWarden can connect to the Internet for direct monitoring, setup, and data
interface by adding the PW-Plus communication module which adds WIFI and Ethernet.
tDATA: MiniWarden will record up to 8192 lines of data with the built in internal memory. There is no
limit when adding the PW-Plus communication device
tOVERFEED 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.
tPROPORTIONAL/SPAN CONTROL: Proportionally reduces the on-time as the measurement gets
closer to the set-point to prevent overshoot.
tE-MAIL ALERTS: The data server provides support for 4 email addresses and 4 phone numbers for
texts.
tPRINTING: Bluetooth printing when adding the PW-Plus communication module.
tSOFTWARE UPDATING: PW-Plus supports immediate software updating over the Internet.

Mounting MiniWarden
Turn off any heaters, pool or spa circulation systems, chemical feed pumps or any related shut-off valves
or equipment and relieve pressure from the filtration system. Find a suitable mounting location near a
120/240 VAC power source that meets the following criteria:
●Facilitates a combined (influent & effluent) maximum tubing run of 30’.
●Do not mount controller above electrical sources or electrical equipment.
●At least 10’ away from any pool, spa or body of water and not accessible to the public.
●Away from corrosive materials and physical hazards.
●Not in direct sunlight or directly above or near any heat source.
●For 240 VAC, ability to hard wire with GFCI (ground fault circuit interrupter) protection.
Securely mount controller or the optional controller backboard vertically on the wall using supplied
screws or appropriate fasteners for the wall construction. Never mount MiniWarden horizontally. Product
shall be positioned such that the power supply cord plug, which is the disconnect device, can be easily
accessible.
Flow Cell To Circulation Plumbing
There are many ways to connect the flow cell tubing to the circulation plumbing. Successful flow cell
installation requires a pressure differential. One way to install is to make sure the input source to the
flow cell is well upstream from any chemical injection point (C Below). The Flow cell input and output
points before and after the filter provide the greatest pressure differential (see below). MiniWarden is
equipped with a strainer to filter out any debris from the unfiltered water. Periodically check and clean
the strainer. However, the flow cell input and output can also be installed before and after the heater if
enough pressure differential is available to create adequate flow through the flow cell.
●Flow Cell Input: Drill & tap a connection point in the circulation system at a location just up-stream
from the filter (A - Below). Install tubing connector and run tubing to the input side of the flow cell.
●Flow Cell Output: Drill & tap a connection point in the circulation system at a location with reduced
pressure just after the filter (B - Below). Install tubing connector and run tubing to the output side
of the flow cell.
CAUTION: Maximum pressure across the sensors should be 10 PSI (pressure gauge may be required).
Always expose the sensors to positive pressure. Prevent exposing the sensors to negative pressure or a
vacuum by connecting the flow cell output tubing to the suction side of the pump as the vacuum may
suck the sensor gel from the sensors rendering the sensors inoperable in a very short period of time.
MiniWarden Installation
MiniWarden Manual • 530-205-4520 • 9
tIf not pre-mounted, find a suitable location to mount the acrylic flow cell within 3 feet of the controller.
Mount and assemble flow cell parts according to Picture 2.
tThere is a small magnet in the flow cell that is held in place with a piece of tape. Remove the tape and
make sure the magnet remains in the hole above the filter / strainer.
Remove pH (Blue) and ORP (Red) sensors from the boxes. Use Teflon tape on sensor threads and all
other flow cell parts to ensure water tight connection and fasten accordingly. IMPORTANT: Remove
the sensor guars that protect the tips.
tInstall the appropriate 1/2” or 3/8” hard vinyl input and output tubing from the pools circulation system
connection points to the “In” and “Out” connection points on the flow cell.
Once connected, turn circulating pump back on, test for leaks at all connection points, and make sure
all air evacuates form the tubing.
IMPORTANT NOTE: There needs to be just enough water flow through the flow cell to raise the flow
magnet inside the flow cell to make contact with the flow sensor. To test this, turn the “input” shut-off valve
to the off position and watch the flow magnet drop from the flow sensor. Next, turn the input shut-off valve
back on and watch the flow magnet raise to the flow sensor. If the flow magnet raises abruptly and
pings/knocks the flow cell acrylic then there is too much flow pressure. To reduce pressure, perform the
same exercise, but now open the shut-off valve slowly and stop when you see the magnet “slowly” raise to
make connection with the flow sensor. Leave the shut-off valve in that position.
